If you are wondering if there’s an easy way to implement an H-bridge driver circuit without using the complex bootstrapping stage, the following idea will precisely solve your query. In this article I have explained how to build an universal full-bridge or H-bridge MOSFET driver circuit, using P-channel and N-channel MOSFETs, which can be used […]

Simple H-Bridge Circuits Using BJTs and MOSFETs | No Need of Driver ICs
An H-bridge is one very useful circuit arrangement which lets us reverse the polarity across a load, so now with one DC supply we can make current flow through the load in both directions alternately. Because of that, these H-bridge circuits get used in many places like DC to AC inverter circuits, transformer drivers, bidirectional […]
Pure Sine Wave Inverter Circuit Using IC 4047
A very effective pure sine wave inverter circuit can be made using the IC 4047 and a couple IC 555 together with a few other passive components. I have explained the details below. Introduction In one of my previous posts I explained the main specifications and datasheet of the IC 4047 where I have explained […]
Can EGS002 Work With a Standard 16 × 2 LCD?
Many people build inverter using EGS002, then they ask can we connect normal 16 × 2 LCD or not?? So the answer is yes, but not the way you may think. Understanding LCD Side Of EGS002 As we all know EGS002 is built around EG8010. That chip is dedicated SPWM sine wave inverter controller IC, […]
How to Upgrade EGS002 Inverter to 5kVA Level
In this article I will explain how to upgrade an EGS002 inverter board to 5kVA power level using the HCPL-3120 or HCPL-J312 opto isolated drivers with isolated inputs and isolated power supply stages. However, the low side MOSFETs are driven through ordinary BJT totem pole configuration such as by using BD139 and BD140 transistor pairs. […]
Parallel MOSFET Calculator Tool: How to Connect MOSFETs in Parallel Safely
The following calculator tool can be used to correctly calculate all the parameters essential for connecting many number of MOSFETs in parallel. This ensures the current handling by the MOSFETs is implemented optimally, without any issues or technical errors, and keeps the MOSFETs safe for long term operations. MOSFET Parallel Calculator Total Load Current (Amps) […]
