MULTI GRADIENT INVERTER - DESIGNING AN INVERTER BASED ON VARIABLE SLOPE VOLTAGE SUMMATION TO OBTAIN AC OUTPUT WITH MINIMIZED THD LEVEL

摘要

The circuit diagram of a multi-gradient inverter system with low total harmonic distortion (THD) in the output is enclosed. The Inverter implements summation of variable voltage slope to obtain the sinusoidal output. The system output voltage is self- stabilized through a feedback loop. The inverter incorporates operational amplifier as integrator to generate variable slope voltage. The summation of these voltages produces the sine wave output. The entire system is designed to give the output with low THD without using the filter circuit.
