Detailed description of the invention
Following present the specific embodiment of a kind of novel Low ESR DC voltage booster circuit that this utility model provides.
As shown in Figure 1, novel Low ESR DC voltage booster circuit is by diode, electric capacity, and switching tube composition charge-discharge modules, power supply VCC is in parallel with each charge-discharge modules；Electric capacity C1, C3, C5, diode D1, D3, D5 and switching tube VT1, VT3, VT6, VT8, VT10, VT11 form a charge-discharge modules；Electric capacity C2, C4, C6, diode D2, D4, D6 and switching tube VT2, VT4, VT5, VT7, VT9, VT12 form a charge-discharge modules；The triggering signal of switching tube VT1, VT3, VT6, VT8, VT10, VT11 connects same signal, and this triggering signal is connected by phase inverter V1 with VT2, the triggering foot of VT4, VT5, VT7, VT9, VT12；R is in parallel with storage capacitor C7 in load.Triggering the positive and negative square-wave pulse that signal uses dutycycle to be 50%, when triggering signal and being high level, switching tube VT5, VT7, VT9 conducting, VT1, VT3 cut-off, power supply charges to electric capacity C1, C3, C5 through D1, D3, D5；After triggering signal becomes low level, switching tube VT5, VT7, VT9 cut-off, switching tube VT1, VT3, VT11 turn on, electric capacity C1, C3, connect with storage capacitor C7 again after C5 series connection, the voltage superposition above C1, C3 and C5 get up after to storage capacitor C7 charging, C7 obtains a high voltage；While C1, C3 and C5 are C7 charging, VT6, VT8, VT10 are also switched on, and power supply passes through diode D2, and D4, D6 are respectively electric capacity C2, and C4, C6 charge；After charging a period of time, trigger signal and become high level, switching tube VT1, VT3 from low level, VT6, VT8, VT10, VT11 end, VT2, VT4, VT5, VT7, VT9, VT12 turn on, C2, C4, C6 is charged to C7 by VT12 after being connected by switching tube VT2, VT4 again, and meanwhile, power supply gives again C1, C3, C5 charge, and so forth.
The operation principle of a kind of novel Low ESR DC voltage booster circuit of this utility model is as follows.
Power supply is alternately to two groups of charge and discharge capacitance charging energy-storings in parallel, after one group of electric capacity charging, utilize switching tube that from parallel connection, this group electric capacity is become series connection, utilize the superposition of multiple capacitance voltage to charge to storage capacitor after voltage is raised, it is achieved the purpose of boosted output voltages；When one group of charge and discharge capacitance is storage capacitor charging, another group charge and discharge capacitance is charged by power supply, and two groups of electric capacity replace discharge and recharge, constantly supply voltage being raised output, higher owing to triggering the frequency of signal, charge and discharge capacitance is for power supply, being approximately short circuit, input resistance is the least.
