Time optimal response control of a two-pole single-phase inverter

Abstract
Transient-free sinusoidal output can be achieved without circuit complexity in today's advanced static inverter where output waveform synthesis is done by time-optimal-response "bang-bang" or by "bang-hang" technique. A reference signal (usually a sine wave) is reproduced with high fidelity and good efficiency (80% to 92%) even under adverse conditions of dc source voltage modulation and non-linear ac loads. A universal single-phase inverter module that uses the time-optimal-response approach becomes effective in either single-phase or 3-phase modular arrays as a "central" as well as a "local" static inverter because it can compensate simultaneously for line and load disturbances.
