摘　　要：介绍1款大功率LED驱动电路,它采用BCD公司的具有原边控制电路的AP3706作为核心控制器,在省略了光耦反馈电路及次级控制电路的情况下,可以实现恒压、恒流高精度输出。对电路在85～264V交流输入电压、不同负载下进行测试,测试结果表明该电路具有结构简单、恒压恒流精度高、稳定性好等优点。This report describes a high-power LED driver circuit, which is based on BCD＇s Primary Side Regulation （PSR） controller, AP3706. It can achieve constant voltage and constant current （CV and CC） regulation without requiring an opto-coupler and secondary control circuitry. The driver circuit was tested at 85-264V AC input voltage under different loads. The experimental results show that the circuit has the advantages of simple structure, high precision constant voltage and current and good stability.
