Electronic Design: IC 555 Inverter Circuit using Mosfet

Inverter Circuit. - This is one of implementation of 555 IC and Mosfet to build power inverter system. It is only need small component completed to build this electronic circuit that basically component.

The electronic design circuit of IC 555 Inverter using Mosfet is look like in Figure 1 below. Other component used like resistors, transformer, capacitors, and transistor.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Description

The electronic circuit design like in Figure 1 above show you power inverter circuit using IC 555 and Mosfet. 

According Eleccircuits blog mentioned that IC-NE555 timer is a square wave frequency generator output of 50Hz. The frequency is determined with R2-resistor and C1-capacitor which we set is 50Hz output. Then we use both N-type Mosfet IRF540 (Q2,Q3) as Driver a transformer coil (primary winding). The current of Pin 3 of IC1 will flow two ways, first through R3 to gate of Q2 and, second ways will flow to Q1-transistor BC549 as inverter logic form to reverse signal difference first ways. Next current flow to gate of Q3 to also dirver the transformer. Them cause have AC voltage of 220V to 250V as voltage of battery source 12V to 14.4V.
