we've tested our inverter circuit on an industrial fan. its working as if it was turned on by an outlet. then we've tested our inverter circuit on a small refrigerator. it wasn't working. we also used an ammeter to measure the circuit, it only read 1.1A max our dc rail is around 315V. is there a way to get to 4.5A? we used the igbt irg4pc50ud in our h bridge circuit
