An Arduino three phase inverter is a circuit which produces a 3 phase AC output through a programmed Arduino based oscillator. In this post I have explained how to make a simple microprocessor Arduino based 3 phase inverter circuit which could be upgraded as per user preference for operating a given 3 phase load. We […]
Phase
Driving 3-Phase Motor on Single Phase Supply
Driving a three phase motor on a single phase supply directly through ordinary methods can be difficult and dangerous. It requires accurately designed circuits for implementing the operations. Here I have tried to present one such PWM controlled three phase motor driver circuit. I have explained more. The circuit can be understood with the following […]
Simple Triac Phase Control Circuits Explored
In a triac phase control circuit, the triac is triggered ON only for specific portions of the AC half cycles, causing the load to operate only for that period of the AC waveform. This results in a controlled supply of power to the load. Triacs are popularly used as a solid-state replacement of relay for […]
Compact 3-Phase IGBT Driver IC STGIPN3H60 – Datasheet, Pinout
In this post I have explained the datasheet, and the pinout specification of the IC STGIPN3H60 from ST microelectronics, which is perhaps the slimmest and the smartest 3-phase IGBT driver IC featuring in-built IGBTs, rated to work with 600V DC bus and upto 3 amp current, that’s equivalent to almost 1800 VA handling power. 3-Phase IGBT […]
3-Phase Signal Generator Circuit using Opamp
Many a times we find it crucial and handy to possess a true three phase signal for evaluating many different electronic configurations such three phase inverters, three phase motors, converters etc. Since it’s not so easy to incorporate single phase to three phase conversion quickly we find this particular implementation difficult to acquire and enforce. […]
Transistor based 3 Phase Sine Wave Generator Circuit
In this post I have explained a very simple 3-phase sine wave generator circuit, using only three bipolar transistors and a few passive components for initiating the desired three phase output. How it Works Referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled […]
