所提出的电路旨在使电磁发电机收集动能。提出了一种工作在边界导通模式(BCM)的同步分裂电容Boost转换器，将交流输入有效地转换为直流输出。BCM的运行是通过零电流检测(ZCD)控制AC输入实现阻抗匹配来实现的。与以前报道的方法相比，ZCD控制提供了简单性。为了降低功耗和提高效率，该电路拓扑将整流器和功率级结合在一起，同时动态控制功率级。该电路采用0.13μm BiCMOS工艺进行设计和布线。版图后仿真验证了所提出电路的工作原理。
The proposed circuit intends for an electromagnetic generator to harvest kinetic energy. A synchronous split-capacitor boost converter operating in boundary conduction mode (BCM) is proposed to efficiently convert the AC input to a DC output. BCM operation is uniquely achieved through zero current detection (ZCD) control of an AC input enabling impedance matching. The ZCD control offers simplicity over previously reported methodologies. To reduce power consumption and increase efficiency, the proposed circuit topology combines the rectifier and power stage while dynamically controlling the power stage. The proposed circuit is designed and laid out in 0.13 μm BiCMOS technology. Post layout simulations verify the operation of the proposed circuit.
