Popis: | Self-powered realization for synchronous switching circuits is a hot spot for piezoelectric vibration energy harvesting. Two typical kinds of switches, bipolar junction transistor (BJT) or metal–oxide semiconductor field effect transistor (MOSFET) are popularly used without a clear understanding about the performance difference. In this paper, comparative investigations about adopting these two types of switches based on a case study are performed. It is determined that the performance difference comes from three aspects: the gate parasitic capacitance, the turning-on threshold, and the driven mechanism. In particular, the third one imposes a critical influence on the performance. Investigations are performed on the self-powered synchronous switching circuit of two possible methods: with electronic breakers or with external control units. The results from simulations and experiments show that the current-driven mechanism limits the available performance in the case of the BJT switch in comparison with the case of the MOSFET switch. The difference is especially obvious for the cases of large piezoelectric capacitance and open-circuit voltage. A preliminary design guideline is concluded that the MOSFET is probably a better choice with the same voltage and current ratings in most cases. |
