Example Embodiment
[0040] Example 1, please refer to figure 2 , A low-ripple high-voltage power supply and its design method, including a loop composed of a main circuit, a driving circuit, a control circuit, and a sampling circuit connected in sequence. The main circuit includes a single-phase rectifier bridge circuit, and the input of a single-phase rectifier bridge circuit , The output ends are respectively connected to the mains power supply and the half-bridge inverter circuit. The output end of the half-bridge inverter circuit is connected to the absorption circuit. One end of the absorption circuit is connected to the primary side of the step-up transformer, and the other end is connected to the resonant inductor. The primary side of the step-up transformer is connected in series; the secondary side of the step-up transformer is connected with the input end of the voltage doubler rectifier circuit, and the output end of the voltage doubler rectifier circuit is connected with the sampling ci...
Example Embodiment
[0052] Embodiment 2, a design method of a low-ripple high-voltage power supply, including the steps:
[0053] S1: First derive the equivalent circuit of the voltage doubler circuit. The voltage doubler rectifier uses a pumping method to obtain a higher output voltage, and the voltage stress of the rectifier device is relatively small. Under the premise of a certain output voltage, the more voltage doubler stages, the smaller the transformer ratio, which reduces the design difficulty of the transformer to a certain extent. The present invention uses such Figure 5 The C-W half-wave voltage doubler rectification shown.
[0054] The n-level voltage doubling can be understood as the series connection of n double voltage circuits. Figure 5 In, except C s1 The voltage at both ends is outside the peak output voltage of the secondary side of the transformer, other C s2 ~C s2n The voltage at both ends is twice the peak output voltage of the secondary side of the transformer. Set the cha...
