This final project aims to make push-pull converter used power supply 220 V, 50 Hz inverter. The accumulator battery used as the source is 24 Ah A sealed lead acid (SLA) with a nominal voltage of 12 volts. The battery of this accumulator is as a voltage source from a push-pull dc-dc converter circuit whose output will be used for a 220 V, 50 Hz Inverter Power Supply. The test results for both t…
