Power supply voltages in Japan include 100 V, which is mainly used for general households, and 200 V, which is used for industrial facilities. However, in the field of research and development, higher voltages are required to operate equipment and perform simulations under various conditions.

In particular, electron microscopes, X-ray inspection equipment, optical communications, and space science experiments require strong electric fields to detect and control the electrons in the elements. In order to create a strong electric field, high voltage is essential.

A high voltage power supply is used when a high voltage is required in this way. A high voltage power supply converts the DC or AC input voltage into a high voltage using an internal power conversion circuit. Unlike general power supplies, high-voltage power supplies require stable voltage and current. For this reason, some high-voltage power supplies have built-in technology to stabilize the output.

Matsusada Precision mainly refers to power supplies with a rated output of 1,000 V or more as high-voltage power supplies, and we have an extensive lineup and a long track record. In addition to high-voltage power supplies, we also offers an extensive lineup of DC stabilized power supplies, AC power supplies, and bipolar power supplies.

The "Cockcroft-Walton circuit method" is one of the high voltage generation methods for high voltage power supplies.

Cockcroft-Walton rectifier circuit
It consists of a multi-stage combination of capacitors and diodes. By increasing the number of stages in the Cockcroft-Walton circuit, the voltage is increased to the desired level.
