10 High Voltage Converter Manufacturers in 2023
This section provides an overview for high voltage converters as well as their applications and principles. Also, please take a look at the list of 10 high voltage converter manufacturers and their company rankings.
What Is a High Voltage Converter?
A high voltage converter is a device that converts high voltage currents, such as 200 V and 400 V, which are industrial voltages. A converter that converts AC current to DC current is called an AC/DC converter, and a converter that converts voltage from DC current to DC current is called a DC/DC converter. Most AC/DC converters use diodes such as MOSFETs to convert AC to DC by switching, while DC/DC converters use resistors or other components to cause a voltage drop, thereby varying the voltage.
Uses of High Voltage Converters
High voltage converters are used in many industries that use high voltage industrial power supplies. Uses of these converters include supplying power to drive industrial DC motors, converting industrial equipment that operates on DC current from AC current, and dropping the voltage to convert it to the rated current to drive the equipment. When selecting high voltage converters, it is necessary to consider whether it is compatible with the current and voltage to be used, size, loss, insulation performance, and safety.
Principle of High Voltage Converters
The operating principles of high voltage converters are explained separately for AC/DC and DC/DC.
- AC/DC High Voltage Converters
An AC/DC high voltage converter consists of an AC power connection terminal, a DC power supply terminal, a MOSFET diode, and so on. The diodes are generally arranged in a diamond-like arrangement of four. The switching nature of MOSFETs is used to convert AC current to DC current. When the AC current passes through the diamond-shaped group of diodes, the current in the positive direction passes through as it is, and the current in the negative direction passes through with the sign switched to the positive direction. In this way, AC current is converted to DC current. - DC/DC High Voltage Converters
A DC/DC high voltage converter may have a resistor connected to the converter, a transistor, or a transformer. With resistors, the resistors are placed on the circuit to cause a voltage drop, thereby reducing the voltage. With a transistor, switching reduces the total voltage by transmitting the current like a pulse wave. A transformer causes a voltage drop according to the number of coil turns. It is also possible to increase the voltage according to the number of coil turns.
