100 Watt Inverter Circuit
100 Watt Inverter Circuit using IC CD4047 and MOSFET: The circuit is simple low cost and can be even assembled on a veroboard, CD 4047 is a low power CMOS astable/monostable multivibrator IC. In this 100 Watt Inverter Circuit, it is wired as an astable multivibrator producing two pulse trains of 0.01s which are 180 degrees out of phase at the pins 10 and 11 of the IC.
100 Watt Inverter Circuit
100 Watt Inverter Circuit IC CD4047 Pin 10 is connected to the gate of Q1 and pin 11 is connected to the gate of Q2. Resistors R3 and R4 prevents the loading of the IC by the respective MOSFETs. When pin 10 is high Q1 conducts and current flows through the upper half of the transformer primary which accounts for the positive half of the output AC voltage.
