50W Inverter Circuit 12VDC to 220VAC based MOSFET FQB45N03

Here the 50W inverter circuit build based power MOSFET FQB45N03 and IC TL494. This inverter will convert 12-14V DC input from car battery, become 220V AC output with 50Hz sine wave frequency. The main oscillator, a voltage reference and comparator collected on DA2. External elements DD1 and DD2 repeated internal structure of the TL494, in […]
