摘　　要：DC-DC开关电源以其高能量转换效率而得以广泛应用,电感的正确选择对于DC-DC开关电源是非常重要的,电感选择正确,电路效率最高,否则电路效率会很低.给出电路转换效率与电感选择及电感电流波形的关系,根据此电感选择方法,能更好地提高工程应用中DC-DC开关电源能量转换效率.DC -DC switching power supply with its high energy conversion efficiency and can be widely used,The inductance of the correct choice for DC - DC switching power supply is very important, Choose the right inductance, circuit efficiency is the highest, or circuit efficiency will be very low. We give the circuit conversion efficiency and inductance selection and inductance current waveform, the relationship between the inductance selection method, can better improve the engineering application of DC - DC switching power supply energy conversion efficiency.
