A DC to AC inverter based on the delta modulation principle

A power DC to AC inverter which is based on the delta modulation principle is suggested in the present work. The delta modulator inverter (DMI) has on RL load and is driven by on appropriate modulator circuit. It Can give an approximate sine wave output of variable frequency and amplitude. The DMI is also able to give other waveforms following the form of input reference signal. The performance of the proposed inverter is analysed.
