EPC’s new development boards can be configured as either a buck converter or a ZVS class-D amplifier, demonstrating reduced losses at high frequency using an eGaN FET synchronous bootstrap augmented gate drive.
EL SEGUNDO, Calif.— March 2016 — Efficient Power Conversion Corporation (EPC) Introduces the EPC9066, EPC9067, and EPC9068 development boards, which are configurable to a buck converter or as a ZVS class-D amplifier. These boards provide an easy-to-use way for power systems designers to evaluate the exceptional performance of gallium nitride transistors, enabling the designers to get their products into volume production quickly. All three boards feature a zero reverse recovery (QRR) synchronous bootstrap rectifier augmented gate driver to increase efficiency at high frequency operation, up to 15 MHz. The boards can produce a maximum output of 2.7 A in the buck and ZVS class-D amplifier configurations. Loss reduction is realized across the entire current range.

In this installment, we present a method to design a suitable EMI filter that can reduce unwanted frequencies to levels within radiated EMI specifications, and do this without negatively impacting the performance of the wireless power coil. In addition, the overall radiated EMI design aspects will also be covered.
