Description
Summary:In this paper, a novel voltage modulation technique named unified PWM (pulse width modulation) for high performance voltage generation in a voltage-fed inverter is described. As increasing the interest in the high quality power conversion is, a simple PWM scheme that has the wide fitness to the general prospect for the loss minimization and the lowest current harmonic with full DC link voltage utilization is required. From the synthesis of the actual inverter action, a simple but useful concept for the 'effective time' is established. And, fully employing this concept, a new voltage modulation technique for various applications is presented with detailed explanation and actual test results. Implementing this facile strategy to actual fields will result in great reduction of calculation efforts and high applicability including the minimization of switching loss and current harmonics.
