For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. Based on the embodiments of the present application, every other embodiment that a person skilled in the art would obtain without making any inventive effort is within the scope of protection of the present application.
Prior to the present application, a conventional manner of driving a plurality of IGBT devices connected in parallel is to control a driving circuit corresponding to each IGBT leg by a controller, so as to drive the IGBT devices to be turned on or off. However, in the existing manner, the control signals sent by the controller to each driver are often asynchronous, or the driving signals sent by different drivers to different IGBT branches are not synchronous, so that current flowing through a plurality of parallel IGBT devices is unbalanced, that is, when part of IGBT devices work, current is insufficient, and part of IGBT devices are overloaded, which greatly reduces the reliability of the IGBT devices, and meanwhile, the circuits applied by the IGBT devices are abnormal.
Based on this, the embodiment of the application provides a driving control device for an IGBT, which can overcome the problem that current imbalance occurs in parallel IGBT devices, thereby avoiding the reliability reduction of the IGBT devices and avoiding the circuit abnormality applied to the IGBT devices.
Referring to fig. 1, fig. 1 shows a schematic structural diagram of a driving control apparatus for an IGBT according to an exemplary embodiment of the present application.
As shown in fig. 1, the drive control apparatus includes: a plurality of IGBT legs L1, L2 … … Ln connected in parallel, a controller 10 and a driver 20;
the first end of the controller 10 is connected with the first end of the driver 20, the driver 20 comprises a plurality of second ends, each second end of the driver 20 is respectively connected with the first end of each IGBT leg, and the second end and the third end of each IGBT leg are respectively connected to the first end and the second end of the circuit to be rectified 30;
the controller 10 is configured to send a control instruction to the drivers 20, where the drivers 20 send driving signals to each IGBT leg simultaneously through the second end of each driver 20 to drive each IGBT to turn on or off in response to the control instruction. Thereby realizing the rectification of the circuit to be rectified 30.
Specifically, the controller 10 may transmit control instructions to the driver 20 in response to a trigger operation by a user, where the control instructions transmitted by the controller 10 to the driver 20 include an on control instruction and an off control instruction.
For example, the controller 10 may send a high level signal (on control instruction) to the drivers 20 in response to a trigger operation by a user, and the drivers 20 send a high level signal (driving signal) to each IGBT leg simultaneously through the second end of each driver 20 in response to the high level signal to turn on the collector and emitter paths of the IGBT devices, and the IGBT devices are driven to be turned on, so that the circuit to be rectified 30 is in a rectifying state, thereby achieving rectification of the circuit to be rectified 30.
Since the plurality of IGBT legs are controlled by one driver 20, in this way, the driver 20 can send driving signals to different IGBT legs through the one driver 20 after receiving one control signal, so that the problem of unbalanced current flowing through the plurality of IGBT devices connected in parallel caused at the instant of the turn-on of the IGBT devices is avoided.
In addition, in the related art, due to the characteristics of the circuit to be rectified 30 itself, as the on time of the circuit to be rectified 30 is prolonged, the current flowing through the IGBT devices in each IGBT leg may be different, resulting in a phenomenon in which the currents of the plurality of IGBT devices are unbalanced during rectification. In order to prevent this, the present application proposes a way in which the current flowing through the IGBT devices in each IGBT leg can be adjusted in real time during the rectification of the rectifying circuit, to improve the reliability of the IGBT devices.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a driving control apparatus for an IGBT according to another exemplary embodiment of the present application.
As shown in fig. 2, the drive control apparatus further includes: sampling circuits M1 and M2 … … Mn and a regulator 40 which are in one-to-one correspondence with each IGBT branch;
a first detection node P1, P2 … … P3 is led out from between the third end of each IGBT leg and the second end of the circuit to be rectified 30, the first end of each sampling circuit is connected to the corresponding first detection node, for example, the first end of the sampling circuit M1 is connected to the first detection node P1, the first end of the sampling circuit Mn is connected to the detection node Pn, the second end of each sampling circuit is connected to the second end of the controller 10, the third end of the controller 10 is connected to the first end of the regulator 40, and the second end of the regulator 40 is connected to the third end of the driver 20;
each sampling circuit is used for collecting current flowing through a corresponding IGBT branch and sending the collected current to the controller 10;
the controller 10 is configured to determine a reference current and a current to be adjusted based on a current of each sampling circuit, generate a deviation signal based on the reference current and the current to be adjusted, and control the regulator 40 to regulate a driving signal output by a second end of the driver 20 corresponding to a target IGBT leg corresponding to the current to be adjusted in the driver 20 according to the deviation signal, so that the second end of the driver 20 corresponding to the target IGBT leg outputs the adjusted driving signal.
Here, the reference current is a current as a reference value among currents corresponding to all IGBT legs. Here, the controller 10 may determine the reference current using any one of the prior art based on the current of each sampling circuit.
As an example, the controller may take, as the reference current, a current having a mode current value corresponding to the current of all the sampling circuits. As another example, the controller may take, as the reference current, a current having a median current value corresponding to the currents of all the sampling circuits.
After determining the reference current, the controller determines other currents than the reference current among the currents of all the sampling circuits as currents to be adjusted.
Next, a specific example will be given of a processing procedure of the controller in a case where the controller takes, as a reference current, a current of which current values corresponding to currents of all sampling circuits are mode. For example, when the parallel IGBT legs are three groups (i.e., n=3), the sampling circuits M1, M2, and M3 collect currents I1, I2, and I3 flowing through the IGBT legs L1, L2, and L3, respectively, and send the currents I1, I2, and I3 to the controller 10, respectively, assuming that the currents I1, I2, and I3 are 0.2A, and 0.1A, respectively, the controller 10 determines a reference current to be 0.2A, and a current to be adjusted to be 0.1A based on the current of each sampling circuit, and then the controller 10 is configured to generate a bias signal (a signal corresponding to the bias of 0.1A) based on the reference current 0.2A and the current to be adjusted, and then control the regulator 40 to adjust a driving signal output from a second end of the driver 20 corresponding to the target IGBT leg (L3) of the target IGBT leg 20 according to the bias signal, so that the second end of the driver 20 corresponding to the target IGBT leg outputs the driving signal (the driving signal to be adjusted to be the driving signal flowing through the driver leg 0.2A after the second end of the target IGBT leg is adjusted to be 0.2).
Because the feedback link is added on the basis of the driving control equipment shown in fig. 1, the acquisition and adjustment of the current flowing through each IGBT branch circuit can be realized in real time by the mode, and the current flowing through the IGBT device in each IGBT branch circuit can be adjusted in real time, so that the current flowing through a plurality of IGBT devices connected in parallel is balanced, and the reliability of the IGBT devices is improved.
