摘　　要：从实际应用出发,设计出了一种可调频率、可调占空比的磁共振式无线充电装置,该装置具有电能转化效率最高模式和充电输出功率最大模式双重功能。在触发信号与LC振荡回路共振时,占空比对充电模式起了决定性作用。在额定输入电压下,占空比在0.20~0.35范围内,装置的电能转化效率最大;占空比是0.6时,装置的输出功率最大。For the practical application, we designed the magnetic resonance wireless charging equipment with an adjustable frequency and an adjustable duty ratio. The equipment has demonstrated two functions, i. e., the highest energy conversion efficiency mode and the charging maximum output power mode. Under the resonance of the trigger signal and LC tank,the duty cycle of trigger signal played a decisive role in the charging mode. Under rated input voltage,the energy conversion efficiency of the device is the largest with the duty ratio in the range of 0.20 to 0.35; under the duty ratio of 0.6, the output power of the device is greatest.
