Normally, for standard 220V AC household projects, a single 600V or 800V TRIAC is more than enough. But what if you are working with a very high voltage line, like 1000V AC? A single common TRIAC will immediately burn and short circuit because it cannot handle that much voltage stress. To solve this, we can […]

High Current Motor Control Circuit using Arduino
In this project, I have explained how to control motor speed using Arduino PWM circuit, and how to implement reverse forward or direction control in a DC motor using Arduino through a couple of push button switches. Any high current motor upto 30 amp can be controlled using this set up. Introduction Motor is a […]
High Voltage, High Current Buck Converter Circuit using Isolated Gate Driver
This is a high voltage 310V to 60V buck converter, so we have that big 310V DC coming in which we usually get after rectifying 220V AC mains. So now that high DC is there and we want to push it down to something like 60V or lower for battery charging or similar work. Audio/Video […]
How to Connect Triacs in Parallel for High Current Loads: Circuit Diagram
Sometimes we make electronic circuit designs, and then we see that one single TRIAC cannot take all the big current of a very heavy load. This heavy load can be a huge heater, a big motor, or too many lights. In this condition, we get a simple idea. We think that we can connect two […]
Calculator to Design a High Power 3kW PFC (Power Factor Correction) Circuit
In this post I will explain how to use this active PFC calculator for calculating high current, high PFC designs. In our example we will be using 230 VAC input and 3 kW output and Vout equal to around 390 V, and we will try to see how each resistor and capacitor gets calculated in […]
High Current 209A, 75V MOSFET IRFP2907 Datasheet
In this post I have explained the main features datasheet of high current N-Channel mosfet IRFP2907 which is rated to handle up to a staggering 209 amps of continuous current at a reasonably massive 75 volts. High Current Specs With the advent of mosfets, switching huge power through compact packages has become particularly feasible. Take […]
