Alternator with controllable frequency and amplitude

Abstract

The article discusses two types of power converters for obtaining sinusoidal signals at the output with the desired amplitude and frequency. In the first case, the source of energy is a constant voltage, in the second - a three-phase voltage source. In both cases, the output value of the converter is a sinusoidal voltage without higher harmonics. In the second version, the power factor of the consumed energy is one. Low power part of the alternator is nonlinear dynamic system generating the desired signal in sliding mode. Then the signal is tracked in high power part in sliding mode as well.
