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 […]

Phase Shift Oscillator Circuits – Wien-Bridge, Buffered, Quadrature, Bubba
A phase-shift oscillator is an oscillator circuit designed to generate a sinewave output. It operates with a single active element such as a BJT or an op amp configured in an inverting amplifier mode. The circuit arrangement creates a feedback from the output to the input through using an RC (resistor/capacitor) circuit arranged in a […]
Arduino 3 Phase Inverter Circuit with Code
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 […]
