摘要
以SEPIC拓扑电路为主电路,采用L6562和TSM101,进行了功率因数校正和LED恒压恒流控制。实验结果证明,设计的电源实现了临界连续模式下,SEPIC电路的高功率因数和较宽范围的恒压恒流输出,成功驱动了LED灯源。
Power factor correction (PFC) and LED constant voltage and current control are com- pleted with taking advantage of SEPIC topological circuit and L6562 chip and TSM101. The experi- mental results prove that the power achieves high PF of circuit and wide range of constant voltage and current output in boundary conduction mode (BCM) and driving LED successfully.
