Embodiment
The embodiment of the present invention is elaborated below in conjunction with accompanying drawing, but not formed to the claims in the present invention
The limitation of protection domain.
As shown in figure 1, existing internal storage battery is gone here and there for several 2V cells B1, B2, B3, B4, B5, B6 ... Bn
Connection forms.
The cell of internal storage battery is divided into six battery packs by the present embodiment, and each battery pack can be a monomer
Battery is connected into a battery pack as a battery pack or multiple cells.Such as can be with independent monomer
Battery B4 is a battery pack；Can also be that multiple cell B1, B2, B3 are connected into a battery pack.
Each battery pack is connected respectively an intelligent series boosting circuit and forms a tandem type BOOST Top Modules
Block.As shown in Fig. 2 the output voltage of six tandem type BOOST topography modules is sequentially connected in series as positive and negative, it is afterwards load supplying.
Each tandem type BOOST topography modules are respectively controlled by controller MCU output PWM ripples, controller MCU operating voltage
There is provided by one of battery pack.
In the present embodiment, 6V battery packs are connected into by 3 2V cells B1, B2, B3, it is powered controller MCU.
It is as shown in Figure 3 that the battery pack correspondingly connects intelligent series boosting circuit composition tandem type BOOST topological structures.Switching tube Q11,
Q12 exports the control of PWM1 signals by controller MCU, and switching tube Q11, Q12 grid share same PWM1 signals.The switch
Pipe Q11, Q12 are MOSFET pipes.
When switching tube Q11, Q12 are closed, the current direction in a loop is：By battery pack anode through inductance L11,
Switching tube Q11 returns to the negative terminal of battery pack.The current direction in another loop is：By the anode of battery pack through switching tube Q12, electricity
Sense L12 returns to the negative terminal of battery pack.Now, inductance L11, L12 storage energies.
When switching tube Q11, Q12 disconnect, a current loop is formed by inductance L11, diode D11 to electric capacity C11；
By inductance L12, diode D12 another current loop is formed to electric capacity C12.Now, energy transfer is stored in electricity by inductance L11
Hold C11；Energy transfer is stored in electric capacity C12 by inductance L12.
