Asymmetric dual-output resonant converter

The utility model discloses an asymmetric dual-output resonant converter which comprises a converter TD, a switching tube, a sawtooth wave generator module, a constant conduction module and a driving module. The converter TD samples an output voltage Voa and is connected to the sawtooth wave generator module, and the constant conduction module samples the output voltage of the sawtooth wave generator module, compares the output voltage with a reference voltage, and triggers the driving module to control the on and off of the switching tube; the driving module comprises at least two driving circuits, and one of the driving circuits is connected with an inverter NOT. According to the utility model, by arranging the asymmetric resonant converter, the output voltage range of the converter is widened. 本实用新型公开了一种非对称双输出谐振变换器，包括变换器TD和开关管、锯齿波发生器模块、恒定导通模块和驱动模块；所述变换器TD采样输出电压Voa并连接到锯齿波发生器模块，所述恒定导通模块采样锯齿波发生器模块的输出电压与基准电压进行比较，并触发驱动模块控制开关管的导通与关断；所述驱动模块包括至少两个驱动电路，且其中一个驱动电路连接有反相器NOT。本实用新型通过设置非对称形式的谐振变换器，以拓宽变换器的输出电压范围。
