Be illustrated in figure 5 as present embodiment MCU control circuit and civil power power down backup battery control switching circuit schematic diagram, its effect and function specifically have: 1, civil power detection of power loss.2, civil power power down backup battery switches.3, exchange input overvoltage, under-voltage detection and protection.4, the environment excess temperature detects and protection.5, fan temperature speed regulating control.6, exchange output time-delay control.7, each functional module electrifying timing sequence control of the slow startup of input, pfc circuit, DC/DC translation circuit.8, various abnormality alarm signal outputs.9, tremble signal output frequently.Below introduce in detail its operation principle down:
D9, D10, R247, R248, R268, R269, C133, C134, ZD8 form power-fail detection circuit, here according to actual needs in the divider resistance first divider resistance adopt R247, R248, the R268 of three 200K composition of contact, the R269 of a 150K of second divider resistance employing.Because this circuit acquisition testing is the input AC impulse wave, when power down appears in civil power, this circuit can be in several milliseconds wink speed make reflection and give 17 pin of MCU and detect analysis and judgement, if the MCU analysis and judgement is the civil power power down, 6 pin of MCU are exported power-off signal level triggers isolation control circuit U26 at once, trigger the back-up source control switching circuit thereupon and give the power supply of BUCK voltage stabilizing circuit, substitute the dc bus voltage that exchanges the output of conversion just often with this.In case owing to begin to calculate from the civil power power down, ATM Switching Power Supply itself can be kept 40ms and normally export, only need about 20ms operate time and switch altogether from civil power detection of power loss and power down backup battery, so can support the assurance seamless switching from these data, thereby guarantee ATM power supply uninterrupted power supply.
D9, D10, R241, R242, R243, R250, R251, R164, C122, C123, C136, ZD9 form input mains supply over-voltage, undervoltage detection circuit.Similar to Fig. 3, here, the 3rd divider resistance adopts the resistance R 241 of three 390K, R242, R243 to contact in the divider resistance according to actual needs, and other structure is identical with Fig. 3.When civil power overvoltage occurs or when under-voltage; circuit carries out voltage detecting thus; to detect voltage then delivers to 15 pin of MCU and carries out analysis and judgement; if the MCU analysis and judgement is overvoltage or when under-voltage; at this moment 7 pin of MCU output high level is delivered to the breaking circuit of pwm chip; turn-off DC/DC master's power conversion circuit with this, thereby protection ATM Switching Power Supply is not damaged.
The TR1 temperature and resistance; R224 resistance; C121 electric capacity is formed the environment excess temperature and is detected and fan temperature speed governing testing circuit; when ambient temperature changes; circuit carries out temperature detection thus; because TR1 is the temperature and resistance of a negative temperature coefficient; more high its resistance of temperature is more little; 14 pin of MCU detection voltage uprised when ambient temperature was too high like this; as long as the voltage that uprises reaches the corresponding voltage that MCU sets; at this moment 7 pin of MCU are exported the breaking circuit that high level is delivered to pwm chip again; turn-off DC/DC master's power conversion circuit with this, thereby protection ATM Switching Power Supply is not damaged when temperature is too high.This testing circuit another one effect is that the speed governing of fan temperature detects, when temperature changes, the 2 pin output duty cycle square wave of MCU can change along with variations in temperature, and detected temperatures is more high, and the 2 pin output duty cycle square wave of MCU is also just more big, the revolution of the square wave control fan of output this moment is also just more big, opposite situation, the revolution of fan are also just more little, for this reason, improved the useful life of fan greatly, and also improved the useful life of indirect ATM Switching Power Supply.
5 pin of MCU are that the 1KHZ that writes trembles signal output frequently, its signal output is through delivering to the operating frequency concussion pin of PFC behind the integration, She Ji purpose is can reduce PFC when work to a great extent to the interference of electrical network like this, also just improve the EMC index, made it to become more green ATM Switching Power Supply.
The 13 pin JDQ of MCU are the signal output of last electric control input soft-start circuit, the 8 pin P-OFF of MCU are the signal output of last electric control pfc circuit work, 7 pin of MCU are again the signal output of last electric control pwm circuit work, the 10 pin TX of MCU are the signal output that last electric control exchanges the work of time-delay output circuit, more than four signals be each functional module electrifying timing sequence control signal output, She Ji purpose is the impulse current in order to reduce start greatly and to power on like this, avoid sizable input impulse current of ATM system and ATM Switching Power Supply powered on moment generation thus, prevented from making because start powered on moment input impulse current is excessive the risk of city's electric tripping.
9 pin of MCU are various abnormality alarm signal outputs.This signal is received ATM system background monitoring, and signal sends alarm in case take place unusually all thus.
In sum, the uninterrupted ATM power supply of this high energy efficiency high frequency switch power, adopted energy-saving design, efficient has reached more than 90%, has reduced product cost, has improved power-efficient and module reliability, alternating current power failure or power failure have been avoided, client's economic loss can not be guaranteed, and to the shortcoming that the client brings inconvenience, can alleviate the immense pressure that power consumption equipment brings to electrical network.This ATM power supply belongs to green power supply, is the ideal source of having relatively high expectations in the power supply place.
