Abstract:

本发明涉及一种具有漏感能量回收的低纹波LED驱动电源,包括整流电路、隔离型交错并联Boost‑PFC电路、纹波补偿电路和LED负载;电网电源经整流电路整流后与所述隔离型交错并联Boost‑PFC电路相连,所述隔离型交错并联Boost‑PFC电路的输出连接至所述LED负载;所述纹波补偿电路包括反激变换器与漏感能量吸收电路;所述漏感能量吸收电路与所述隔离型交错并联Boost‑PFC电路电性相连,用以吸收隔离型交错并联Boost‑PFC电路中变压器漏感产生的电压尖峰,所述漏感能量吸收电路的输出经所述反激变换器连接至LED负载,为LED负载提供纹波补偿信号。本发明既能实现对输出侧低频纹波的抑制,又提高了变换效率,具有较高的应用价值。
