ABSTRACT

Inverters convert DC to AC in order to feed power to an AC load from a DC system at some desired voltage and frequency. In the application field of power electronic power electronics (PE) circuits, the inverter has much importance, warranting an extensive research such as current control techniques for three-phase voltage source pulse-width modulation PWM converter or analysis of current controllers for voltage source inverter. For control of amplitude and frequency of the inverter output voltage, the firing and regulating circuits are necessary. When a single-phase AC output is required from a DC source, the commonly employed circuit is the full-bridge inverter circuit. Pulse-fed PE circuits can be analyzed using Walsh functions. This orthogonal function set has special advantage of handling theoretically the modulation of pulse width of a system. The analysis is carried out in the Walsh domain, and the results are compared with the exact solutions.
