Abstract: A solid state or static current limiter which provides a relatively low impedance electrical current conducting path between a source of power and a load or between two interconnected sources or networks during non-overload conditions. The main current carrying device comprises a thyristor or similar gated element which is shunted by an auxiliary circuit which includes a capacitive element, a controlled thyristor and an inductance element. The capacitive element is shunted by a current limiting circuit which cooperates with the capacitive element to limit current in the load once the main current carrying thyristor has been turned off and the current flowing therethrough has been commutated into the auxiliary circuit as when an overload or short circuit condition has been sensed in the load. The rate of turnoff of the main thyristor is limited primarily by the inductive element in the auxiliary circuit. The inductive element need not carry appreciable load current for an extended period of time as the main current limiting function for the circuit is provided by forward biasing a diode which is connected in series with a current limiting capacitor shortly after the main thyristor has been turned off.

Abstract: The invention comprises apparatus for comparing the filtered power transformer output waveform of a pulse-width-modulated inverter circuit with an AC reference voltage waveform and generating output voltage signals to control the inverter drive circuit to the extent necessary to produce an inverter output waveform substantially duplicating the reference voltage waveform and substantially void of low order harmonics. An anticipatory signal developed by a circuit which monitors the change in current with respect to time in a capacitor included in a filter circuit connected to the output of the power transformers provides optimum response of the apparatus to changes in the output waveform beyond prescribed units relative to the reference voltage waveform.
