摘要： 提出了基于高功率因数混合型变换器的交流爆闪灯，这种高功率因数混合型变换器可在交流80 V~250 V宽电压范围内工作，单级变换器可实现升压、降压，且功率因数很高，开关管承受的反向电压与输入、输出电压中的较大者有关，当输入电压为较大者，此时开关管反向电压近似为输入电压。当输出电压为较大者，此时开关管反向电压近似为输出电压。因此开关管在较低的反向电压下工作，特别适合于高压输出的场合，提高电路的稳定性和可靠性。利用高功率因数混合型变换器设计的爆闪灯可实现110 V/220 V产品的单一化，因此产品便于维护管理，提高管理效率。

AC flash design for high power factor hybrid converter

Abstract： This article proposes an AC strobe light based on a high power factor hybrid converter. This kind of high power factor hybrid converter can work in a wide voltage range of AC 80 V~250 V. The single-stage converter can achieve boost and step down, and the power factor is very high. The reverse voltage of the switch tube is the same as the output voltage. Therefore, the switch tube works at a lower reverse voltage, which is especially suitable for high-voltage output occasions to improve the stability and reliability of the circuit.The strobe lamp designed with a high power factor hybrid converter can realize the unitization of 110 V/220 V products, so the product is easy to maintain and manage, and improve management efficiency.
