In this paper, a nonisolated dc-ac inverter topology, which enables a true single-stage direct conversion from a single dc input supply to multiple ac output power sources by using only one inductor in the power stage, is proposed. Compared with the conventional multiple-output parallel half-bridge or full-bridge inverters, the proposed single-stage single-inductor multiple-output (SIMO) inverter topology achieves a smaller number of inductors and power switches, high power density, scalability to multiple ac outputs, and independent power controllability for each ac output. A useful application of the proposed SIMO inverter is to drive an array of transmitting coils simultaneously for wireless power transfer applications. An experimental prototype has been developed to demonstrate the effectiveness of a single-inductor three-output boost-derived inverter without cross regulation. Experimental results show that precise and independent peak voltage regulation of each individual sinusoidal ac output is attainable with the proposed SIMO inverter.
