with digital pulse width modulation controller converts the DC bus voltage into three phases, precisely regulating 415V AC voltage of constant 50 Hz frequency. The inverter with digital signal processing controller converts the output voltage into pure sinusoidal form with very low harmonic distortion required for various types of loads. It also accurately monitors, controls and protects the power modules for any fault. Thus, the power conditioner generates constant three phase voltage and constant frequency irrespective of input source.
