SQUAREWAVE POWER OSCILATOR

Description

The device is made of four blocks viz. an oscillator, H-bridge driver, feedback sense circuit and a Voltage regulator. The oscillator generate 400 Hz TTL square wave, is input to the h-bridge driver and Syn. output. In normal operation the H-bridge output is connected to feedback sense circuit which control the voltage regulator to stabilize the output. H– bridge output is short circuit and over load protected with thermal shout down. For transformer couple output, remove short link. Connect primary of transformer to H-bridge output and secondary to sense terminals. Isolated output available at OP-1 & OP-2
