摘要
A multilevel voltage source inverter and related control scheme in which a VSI controller operates in a low frequency mode of operation below a threshold operating frequency to more evenly distribute the duty cycle and thermal loss of the VSI switches. The technique makes use of multiple alternative switching states which achieve the same output voltage.
