PROBLEM TO BE SOLVED: To provide an auxiliary power supply generator.SOLUTION: An auxiliary power supply generator including a main work power supply output end (PL1) and a ground end (GND) and applicable to a filtering power supply circuit is further provided with a first voltage stabilization capacitor, and a second voltage stabilization capacitor connected with the first voltage stabilization capacitor via a first diode. The first voltage stabilization capacitor and the second voltage stabilization capacitor form a capacitor voltage division circuit. A short circuit element and a second diode having a current conduction direction opposite from that of the short circuit element are connected with a first joint between the first voltage stabilization capacitor and the first diode. The short circuit element includes a control end, and is connected with a first Zener diode thereat. A first resistor of appropriate resistance is further connected with the first Zener diode, and also connected with a second joint between the second voltage stabilization capacitor and the first diode. |
