利用E类逆变器抑制感应电能传输系统的电磁干扰

The coupler's antenna-like structure introduces electromagnetic interference (EMI) challenges in inductive power transfer systems. This letter leverages the spread spectrum technique in a class E inverter-driven, highly resonant system to address these challenges. However, a conventional class E inverter would be optimized toward a single frequency, and directly leading to hard switching issue whe...
