Problems solved by technology
[0006] 1. There is no protective device between the drain D and the source S of the switching device of the main circuit (working circuit), such as the field effect tube FET. When the pulse high-voltage power supply is turned on, turned off or the load is short-circuited, the primary coil of the high-voltage package T A self-inductance electromotive force of very high voltage will be generated on the ground, and the drain D and the source S of the field effect transistor FET will be broken down because there is no protection device;
[0007] 2. There is no control pulse indicating circuit and pulse high-voltage indicating circuit, so it is difficult to judge the working state of the pulse high-voltage power supply at a work site without instruments;
[0008] 3. Failure to take technical measures against external strong dry resistance, such as lightning strikes, the pulse high-voltage power supply will be damaged as a result;
[0009] 4. The switching device of the main circuit (working circuit), such as the field effect tube FET, is not provided with a thermal protection device, and the switching device such as the field effect tube FET will be damaged due to overheating;
[0010] 5. The DC voltage of the control pulse generating circuit in the control loop is not added with a secondary voltage stabilizing circuit. When the pulse high-voltage load is ignited, the ignition signal coupled by space or line is easy to damage the devices in the control pulse generating circuit ( e.g. integrated circuit IC)

Description
technical field [0001] The invention relates to the field of high-voltage power supplies, in particular to a core component in plasma purification equipment, that is, a pulse high-voltage power supply that allows short-circuiting of loads. Background technique [0002] Plasma purification equipment is a kind of purification equipment in the field of environmental protection, and the pulse high-voltage power supply is the core component of plasma purification equipment. [0003] Air purification is an important application field of plasma purification equipment. The composition of the air to be treated is very complex, some contain conductive dust, some contain water vapor and so on. The dust or water vapor will deposit on the high-voltage insulation device at the load end of the pulse high-voltage power supply, such as ceramic joints, reducing its insulation, and even appearing in a short-circuit or quasi-short-circuit state, resulting in an increase in the output current o...
