摘要： A two-switch Flyback power converter is disclosed. The two-switch Flyback power converter comprises a transformer, a first switch, a second switch, and a control circuit. The transformer includes a primary-winding and a secondary-winding. The primary-winding has a first winding and a second winding. The first switch is coupled to switch the first winding. The second switch is coupled to switch the first winding and the second winding. The control circuit generates a first-drive signal and a second-drive signal to control the first switch and the second switch for switching the transformer and regulating an output of the two-switch Flyback power converter. The two-switch Flyback power converter with less capacitance of the bulk capacitor or bulk capacitor-less can reduce the voltage ripples at the output voltage for cost saving.
摘要翻译：公开了一种双开关反激式功率转换器。双开关反激式功率转换器包括变压器，第一开关，第二开关和控制电路。变压器包括初级绕组和次级绕组。初级绕组具有第一绕组和第二绕组。第一开关被耦合以切换第一绕组。第二开关被耦合以切换第一绕组和第二绕组。控制电路产生第一驱动信号和第二驱动信号以控制第一开关和第二开关，用于切换变压器并调节双开关反激式功率转换器的输出。具有较小电容大容量电容器或大容量电容器的双开关反激式功率转换器可以降低输出电压下的电压波动，从而节约成本。
