A power supply control system for a power supply having a first half-bridge leg and a second half-bridge leg. In the control system, a first plurality of drive signals are configured to operate a half-bridge as a forward leg while a second plurality of drive signals are configured to operate a half-bridge as a backward leg. A switch element is intermediate the first and second plurality of drive signals and the first and the second half-bridge legs, the switch element being adapted to operate the first half-bridge as a forward leg and the second half-bridge as a backward leg in a first operating mode, the switch element being further adapted to operate the first half-bridge as a backward leg and the second half-bridge as a forward leg in a second operating mode.

An electrical power conversion system having a harmonic distortion limiter. The power conversion system includes a power converter having a power input, a power output, a current measurement output signal, and a control signal input. The system further includes a controller having a voltage control subsystem arranged to measure a voltage present at the power output of the power converter and generate a corresponding current reference signal. A current control subsystem of the controller is arranged to receive the current reference signal and the current measurement output signal and generate a corresponding modulation command signal, the modulation command signal of the controller being electrically coupled to the control signal input of the power converter. The power converter is responsive to the modulation command signal to limit harmonic distortion at the power output of the power converter.

A power control system includes a first switch configured to receive electrical power from a power source and selectably provide the electrical power to a load. A current limiter is intermediate the first switch and the load. A second switch is also configured to receive electrical power from the power source and selectably provide electrical power to the load. The power control system includes a soft-start operating mode wherein the first switch is activated to provide the electrical power to the load, current provided to the load being limited by the current limiter. The second switch is also activated to provide the electrical power to the load, the second switch being activated a predetermined period of time after activation of the first switch. The first and second switches are also deactivated while the voltage of the power source exceeds a predetermined level.
