    • The present invention includes: a transformer having a primary winding, a secondary winding and a tertiary winding; a primary-side rectifying and smoothing circuit, which converts alternating-current power to direct-current power and smoothes the power; a secondary-side rectifying and smoothing circuit, which smoothes secondary-side power; a tertiary-side rectifying and smoothing circuit, which smoothes power of the tertiary winding; a switching circuit, which opens and closes the primary winding; a pulse width control circuit, which controls the pulse width of drive signals that control the opening and closing of the switching circuit; and a secondary-side electrolytic capacitor deterioration detecting circuit, which detects deterioration of the secondary-side electrolytic capacitor. The secondary-side electrolytic capacitor deterioration detecting circuit detects deterioration of the secondary-side electrolytic capacitor by inputting the output voltage of the tertiary-side rectifying and smoothing circuit, and stops operation of a switching power supply circuit.
    • 本发明包括:具有初级绕组,次级绕组和三次绕组的变压器; 初级侧整流平滑电路,其将交流电力转换为直流电力并使功率平滑化; 二次侧整流平滑电路,其平滑次级侧功率; 三级侧整流平滑电路,使三次绕组的功率平滑; 开关电路,其开闭初级绕组; 脉冲宽度控制电路,其控制控制开关电路的断开和闭合的驱动信号的脉冲宽度; 以及次级侧电解电容器劣化检测电路,其检测二次侧电解电容器的劣化。 次级侧电解电容器劣化检测电路通过输入三次侧整流平滑电路的输出电压来检测二次侧电解电容器的劣化,停止开关电源电路的动作。
