Inverter circuit utilizing a frequency synchronization device |
摘要 |
An inverter circuit that can provide a stable AC power supply by synchronizing the switching operations of a DC-to-DC converter and a DC-to-AC converter which constitute the inverter circuit with each other. The inverter circuit includes an error amplifier for comparing a feedback control voltage from the DC-to-AC converter with a reference voltage and amplifying the resultant voltage of comparison, a frequency synchronizing section for providing a sawtooth voltage synchronized with the frequency of a ripple voltage occurring at an output terminal of the DC-to-DC converter due to the switching operation of the DC-to-AC converter, and a comparator for comparing the sawtooth voltage with the output voltage of the error amplifier, and providing a switching control signal to the DC-to-DC converter as result of comparison.
