A power conversion circuit includes a variable voltage converter (VVC) with a stabilizing means for stabilizing its output voltage. The stabilizing means can be in the form of a diode that clamps the VVC output voltage to the VVC input voltage so that the output voltage does not drop below the input voltage when a load imposes a sudden power demand. The stabilizing means also enables a bypass mode in which transient power can be provided from a power source to an inverter without current flow through the VVC inductor or switches. When embodied as a diode, the stabilizing means can increase the maximum power that can be transferred by the power conversion circuit, improve the power response of the circuit, minimize control instability, and reduce power losses.
