In this post we try to investigate how to design a SG3525 full bridge inverter circuit by applying an external bootstrap circuit in the design. The idea was requested by Mr. Mr. Abdul, and many other avid readers of this website. Audio/Video Representation Why Full-Bridge Inverter Circuit is not Easy Whenever we think of a […]

3 Best Transformerless Inverter Circuits
As the name suggests, an inverter circuit that converts a DC input into AC without depending on an inductor or a transformer is called a transformerless inverter. Since an inductor based transformer is not employed, the input DC is normally equal to the peak value of the AC generated at the output of the inverter. […]
90V to 400V Low Voltage Cutoff Circuit for Solar Inverters
Today we are going to discuss a purely analog high voltage protection circuit which is specially designed for solar power systems working with PV voltages from around 90 volts up to 400 volts DC. The main purpose of this circuit is to disconnect the inverter whenever the solar panel voltage falls below a safe level, […]
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 […]
Easy H-Bridge MOSFET Driver Module for Inverters and Motors
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 […]
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 […]
