Abstract: A power generation system includes an input to receive a low-voltage alternating current and a number N of voltage-conversion modules coupled to the input, each electrically connected in series. Each voltage-conversion module includes a transformer configured to convert the low-voltage alternating current into a high-voltage alternating current. Each voltage-conversion module includes a multiplier configured to convert the high-voltage alternating current from the transformer into a high-voltage direct current. The multiplier includes a positive multiplier part and a negative multiplier part. The positive multiplier part and the negative multiplier part each includes a pair of input terminals connected in parallel with the transform and at least one multiplier stage comprising a single diode and a capacitor assembly. The number N is an even number between 4 and 24.

Abstract: An exemplary motor driving system includes a power source, a driving circuit, a controller, a motor, and a protection circuit. The driving circuit including at least one switching device coupled with the power source. The motor includes a plurality of windings. The motor is coupled with the driving circuit and driven by the driving circuit. The controller is configured to provide first switch signals to the at least one switching device of the driving circuit in a normal mode. The protection circuit is coupled with the controller, and configured to generate second switch signals based at least in part on a fault signal in a fault mode and provide the second switch signals to the at least one switching device of the driving circuit so as to reconstruct circuit loops between the driving circuit and the plurality of windings. A method for operating the motor driving system is also described.
