摘要
发射端串联补偿拓扑在基于E类高频逆变器的无线电能传输(WPT)系统中应用广泛。其串联谐振回路存在无载时电流过大,损耗过高等问题。设计一种用于该系统的无载保护控制电路,该电路具有电感电流缓冲及逆变器过流保护功能,且系统发射端在无载时的功耗为0.6 W左右。对于无线电能传输系统的控制电路设计具有参考意义。
Series resonance compensation topology in the transmitting terminal is widely used in wireless power transfer（WPT） systems based on class E high frequency inverter. However,the current of series resonance circuit without load may be too large and may cause high losses. Therefore,non-load protection control circuit for overcoming the problem was designed in this paper,which possesses the functions of inductor current buffer and inverter overcurrent protection. Meanwhile,the power consumption of the transmitting terminal without load is only 0.6W. The designed circuits can contribute to the design of control circuits for WPT system.
