摘　　要：介绍一种适用于低压、宽范围供电的多路输出单端正激DC/DC变换器,其输入电压范围为DC 8～40V,输出为5V/3A、±15V/0.5A、+10V/0.5A。功率电路使用无损耗箝位电路实现了变压器磁芯的复位,控制电路使用第三代BICOMS电流控制型PWM,简化了电路设计、降低了噪声敏感度,并分析了多路输出耦合电感对负载交叉调节性能的影响。A multiple outputs single-end forward DC/DC converter which is very suitable for low-voltage, wide range power supply is introduced. The input voltage range is DC 8-40 V, outputs are 5 V/3 A, ±15 V/0.5 A, 10 V/0.5 A. Nonloss clamping circuit is employed to reset the transformer magnetic core in power circuit. The third generation of BICOMS current control PWM is used to simplify designs and reduce the noise susceptibility. The influence of multiple output coupling inductance to the load cross regulation is analyzed.
