  • Patent number: 10903756
    Abstract: A system and a control method for generating multiple independent alternating current (AC) voltages from a direct current (DC) voltage source in a single-inductor multiple-output (SIMO) inverter are disclosed. The system comprising: a DC voltage source (101) for providing electrical energy; a front-stage DC-DC power converter (105) comprising exactly one inductor as an energy storage element for power conversion and a main switching element; a plurality of selectable output branches (106), wherein each output branch comprises an output selection switch (107), a resonant tank (110), and a transmitter coil (109), wherein the resonant tank converts output power of the DC-DC power converter into AC power for feeding the transmitter coil; and a controller (104) for determining ON/OFF states of the main switching element and the output selection switch of each of the output branches.
