Abstract

The paper proposes an algorithm to calculate the switching angles using harmonic elimination PWM (HEPWM) scheme for voltage source inverter. The algorithm is based on curve fittings of a certain polynomials functions. The resulting equations require only the addition and multiplication processes; therefore, it can be implemented efficiently on a microprocessor. An extensive angle error analysis is carried out to determine the accuracy of the algorithm in comparison to the exact solution. To verify the work ability of the technique, an experimental voltage source inerter was constructed. Since the proposed HEPWM algorithm is simple and fast, it is implemented using a low cost, 16-bit microprocessor.
