Abstract

In applications such as plasma generation and wireless power transfer, high-frequency inverter capable of operating across broad power levels and load impedance is essential. This paper introduces a full-bridge inverter characterized by favorable soft-switching characteristic, which maintains a consistent power output over an extensive range of load and power levels. To facilitate Zero-Voltage Switching (ZVS) and enhance adaptability to a wide load range, dynamic frequency modulation has been implemented. A prototype with 60 V input and 60 W output, functioning at a central frequency of 10 MHz, has been developed and tested in the laboratory. The experimental results substantiate the viability of the proposed inverter design.
