Here we are going to talk deeply about snubber circuits and why we must use them with MOSFET H-bridge circuits. Because if we do not put snubber in H-bridge then that MOSFETs might blow off during switching. Specially when we drive inductive loads like transformer, motor, relay, solenoid, etc. then this thing becomes very serious. […]

Universal H-Bridge Circuit Module
In this article I will elucidate a simple universal H-bridge module using BJTs and N-channel MOSFETs. This module can be integrated with any standard oscillator ICs such as IC 4047 or IC SG3525 or even IC 555, to create a highly efficient H-bridge inverter circuits. Why using 4 N-channel MOSFET H-Bridge is the Most Efficient […]
Simplest Full Bridge Inverter Circuit
Among the different existing inverter topologies, the full bridge or the H-bridge inverter topology is considered to be the most efficient and effective. Configuring a full bridge topology could involve too many criticality, however with the advent of full bridge driver ICs these have now become one of the simplest inverters one can build. What’s […]
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 […]
Arduino Full-Bridge (H-Bridge) Inverter Circuit
A simple yet useful Microprocessor based Arduino full-bridge inverter circuit can be built by programming an Arduino board with SPWM and by integrating a few mosfets with in H-bridge topology, I have explained the details below: In one of our earlier articles I will comprehensively explained how to build a simple Arduino sine wave inverter, […]
How to Make a Bridge Rectifier
A bridge rectifier is an electronic network using 4 diodes which is used for converting an AC input to DC output. The process is called full wave rectification. Here I have explained the basic working principle of rectifier diodes such as a 1N4007 or a 1N5408, and also learn how to connect 1N4007 diodes to […]
