The high-voltage pulse transformer is a special type of electronic transformer. It transforms a unipolar pulse that is close to a rectangle; it is widely used in various electronic equipment as an impedance matching and power adjustment device.(Types of Power Transformer)
In accelerator research, the use of a transformer system instead of a generator can greatly simplify the pulse forming line discharge system. In the high-power microwave system with an explosive magnetic compression generator as the primary energy source, the transformer plays the role of impedance matching and power adjustment to drive high-impedance devices such as diodes to work effectively.
high voltage pulse transformer
Traditional high-voltage air-core transformers mostly use a spiral wound structure. Because each turn is direct to the ground, the insulation problem to the ground is difficult to solve. In addition, the volume of this type of transformer is large and the coefficient of disaster is low, which limits its scope of use.
The use of a foil tape layer winding and a voltage equalizing ring structure can effectively solve this problem, because the ground voltage in the foil tape layer transformer is evenly distributed to each turn, effectively solving the problem of ground insulation due to tight turns. The coupling coefficient is also very high.
When the primary input current, the secondary has no output, the magnetic core converts the input current into magnetic storage and then releases the induced current output on the winding when the input current is cut off. So the pulse transformer is also called an energy storage transformer. At the same time, the pulse transformer has some similarities with the power transformer, that is, it has the function of voltage conversion and isolation.
The high voltage pulse transformer is a transformer that works in a transient state, that is, the pulse process occurs in a short period of time, and it is a square wave with a smooth top, while the general transformer works in a continuous and unchanging magnetization. The variable signal changes according to a sine wave.
