基于UC3843的半波整流电路辅助电源设计
资料介绍
设计了基于UC3843的半波整流电路的辅助电源。先介绍半波整流电路的工作原理,再将半波整流电路与传统的辅助电源获取方式进行相关的定量计算和比照,最后设计半波整流电路的实际电路,并应用在LED恒流驱动器上,半波整流电路的输出电压为12 V。对样机的测试结果表明,本文所设计的基于UC3843的半波整流电路的辅助电源的性能满足设计要求,值得推广。
A design has been developed of the auxiliary power supply of the half-wave rectifier circuit based on UC3843. A brief introduction has been made of the operation principle of the half-wave rectifier circuit, followed by some relevant quantitative calculation and comparison with the acquisition way of the traditional auxiliary power supply. This principle has been applied to the design of the actual circuit, as well as to the LED constant-current driver, with 12 V the output voltage of the half-wave rectifier circuit. The test result of the prototype shows that the performance of the designed auxiliary power supply of the half-wave circuit based on UC3843 meets the design requirements, thus worthy of the marketoriented promotion.
