摘要： According to one embodiment, a power converter circuit includes a resonant circuit coupled to an alternating current (AC) voltage source to convert a first AC voltage to a first AC current and an AC to direct current (AC/DC) converter coupled to the resonant circuit, where the AC/DC converter is to convert the AC current to a DC current. The power converter circuit further includes an inverter coupled to the AC/DC converter to convert the DC current to a second AC current, an AC filtering circuit coupled to an output of the inverter, and a load coupled to the output of the inverter to convert the second AC current to a second AC voltage.

摘要： According to one embodiment, an AC power system includes a first AC/DC converter to be coupled to a direct current (DC) load and a multi-phase AC power supply. The system further includes a second AC/DC converter coupled in parallel with the first AC/DC converter via an interphase transformer to the DC load and the multi-phase AC power supply. The system further includes a controller coupled to the first and second AC/DC converters, where the controller is configured to generate a gate trigger signal for firing each of the rectifiers for the first and second AC/DC converters. During a first power cycle, a rectifier of the first AC/DC converter is fired at a firing angle advanced to a firing angle of a corresponding rectifier of the second DC/DC converter. During a second power cycle, the rectifier of the first AC/DC converter is fired at a firing angle lagging to a firing angle of the corresponding rectifier of the second AC/DC converter.

摘要： A fault current limiter includes a rectifier having AC terminals and direct current (DC) terminals, the AC terminals to be coupled to an AC power source and a load. The fault current limiter further includes a DC diode coupled in parallel across the DC terminals of the rectifier and a DC reactor coupled to the DC diode. When an AC current drawn from the AC power source is less than a predetermined threshold, the DC diode is in a forward bias state to allow the AC current flowing to the load through the DC diode. When the AC current drawn from the AC power source is greater than or equal to the predetermined threshold, the DC diode is in a reverse bias state, forcing the AC current to flow to the load through the DC reactor.
