Inverter power supply

摘要: An inverter power supply operating at a high efficiency to provide an AC voltage load. The source includes DC and output transformer with primary winding, secondary feedback winding. FET is connected in series the winding across source. capacitor form L-C resonant circuit which, response switching of FET, provides oscillation be applied through drive load, while inducing allowed go negative point between A biasing apply offset which additive so as give bias FET. characterized include level detector issues zero signal when detected lower least level, pulse generator signal, produces predetermined pulse-width overrides such manner enable turn on for ON-period determined by only after lowered whereby avoiding from flowing current still positive therefore reducing loss.
