Static Inverter With Synchronous Output Waveform Synthesized By Time-Optimal-Response Feedback
Andress Kernick, D. L. Stechschulte, D. W. Shireman · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1977
Time-optimal-response ``bang-bang'' or ``bang-hang'' technique, using four feedback control loops, synthesizes static-inverter sinusoidal output waveform by self-oscillatory but yet synchronous pulse-frequency-modulation (SPFM).
