The single-ended resonant inverters, such as a Class-E inverter, are suitable for tens of megahertz switching due to the soft-switching characteristics. However, maintaining the soft-switching characteristics and constant output power under wide load variation is a challenging issue in the single-ended resonant inverters. This paper proposes the design and control method to maintain the soft-switching characteristics and constant output power. The proposed method utilizes variable switching frequency, duty adjustment, and variable DC input voltage. With the proposed method, a higher power density can be achieved compared to conventional systems with a complex and bulky impedance matching network. Design methods for the series L-C filter and the Class-E inverter for wide load variation are also explained. The experimental results from 12-15 MHz, 200 W Class-E resonant inverter prototype board verify the validity of the proposed design and control method.
