Simple Gate Open/Close Controller Circuit
The simple gate open and close controller circuit is designed to operate the gate through a couple of push buttons manually, it can be also modified for implementing the activation through a remote control. How it Works Referring to the shown, simple gate open, close controller circuit below, we can witness a rather straightforward configuration, […]
Convert any H-Bridge Inverter to Sine Wave H-bridge Inverter
In this post we’ll discuss how to convert any ordinary square wave H-bridge inverter into an almost pure sine wave inverter circuit. Basic Concept The idea is simple, just chop the low side MOSFET gates of the H-Bridge with reverse SPWM (Sinusoidal Pulse Width Modulation) waveform. This will force the low side 50 Hz, or […]
