| Summary: | Wireless power transfer (WPT) technology has attracted a wide concern in both academia and industry. Since the operating frequency of the WPT system is usually pretty high, the switching loss thus presents seriously and the soft-switching technology is urgently demanded. A WPT system with modified circuits and control methods is proposed in this paper. What is more, multiple means of soft-switching are analyzed and introduced into WPT system.
The designed WPT system uses full bridge converters on both transmitter-side and receiver-side. The mutual inductor is series-series compensated. A pulse width modulation (PWM) is adopted to control the transmitter-side inverter and the receiver-side converter is controlled by zero current detection (ZCD) technology. The output voltage is regulated by a buck converter. In order to achieve soft-switching, the whole component of transmitter-side is designed to be a little inductive and the receiver-side could achieve soft-switching by ZCD technology as well.
Finally, all these designs are verified by the simulation on Piecewise Linear Electrical Circuit Simulation (PLECS) platform. |
