A 13.56MHz class e power amplifier for inductively coupled DC supply with 95% power added efficiency (PAE)

  • Recent development of GaN power transistors with blocking voltages up to 650V enables novel power electronics applications with outstanding performance in high-frequency operation. This paper demonstrates a class E power amplifier with 13.56MHz switching frequency for inductively coupled DC power supplies. Continuous wave output power up to 200W is achieved with 95% Power Added Efficiency (PAE).
