An analysis of delta modulated PWM inverter
Abstract
This paper presents an analysis of a voltage source delta modulation (DM) inverter. The delta modulation method provides several advantageous characteristics over commonly used sine modulation process. It is relatively easy to implement and provides low harmonics at the inverter output. The inherent features of the delta modulation also provides control of ratio of voltage to frequency and commutation numbers of an inverter without much complexity in control circuit. These and other features of DM inverters are investigated theoretically and verified experimentally.
