Combination of class e inverters with DC-DC converters for a circuit design with controllable dual outputs

This paper proposes a circuit that combines the class E inverter with DC-DC converter so as to provide dual controllable outputs. This study is motivated because the industrial equipment often needs different voltage sources to operate, yet with an inadvertent choice of parameters in the isolated converters, the voltage quality is often highly affected. Therefore, by connecting an auxiliary power switch and a diode in series between class E inverter and DC-DC converter, a circuit with dual controllable outputs is suggested. Moreover, the input inductor and a power switch in the class E inverter are shared with DC-DC converter for the energy storage, hence reducing the number of elements when compared to published techniques. This proposed circuit is completed with hardware experiments performed under different load conditions. Test results support the practical values of this proposed circuit for supplying source applications.
