Abstract
A novel power inverter system for transferring electric power between a DC power source and a multi-phase electric machine is described, and includes a power inverter, a Z-source inverter, a first switch, and a second switch. The first switch is arranged between positive and negative conductors of a high-voltage bus that is electrically coupled to the DC power source, and the second switch is arranged in-line on the positive conductor of the high-voltage bus.
