Power Supplies for Telecom and Datacom

Technology Advancement through Synergy Effects
Technological innovation in the field of communications makes people's eyes pop open. Through the generations when communication was expanded wider and to more remote places by means of the submarine cables and satellites, technologies have been digitized for more efficient and more stable communications. With the age of multimedia, a gift child from a god in the age of advanced information now setting in, optical fiber is in use for the communication lines and the mobile telephones and personal computer communications are rapidly spreading. To meet all of the requirements of these latest means of communications, still more advanced technologies are demanded.
Since 1944 when Origin first delivered the selenium rectifiers to then Ministry of Post and Telegraph, the company grew abreast of technological innovations. It developed many devices and equipment to meet the technical needs of the communications industries in those days to enjoy a high reputation.

Power Supplies for Industrial High Voltage Equipment

Major Contribution to the Growth of Japanese Industries
Origin has contributed to the growth of Japanese industries in various phases through the development of high voltage power supply units.
Beginning with the power supply equipment for the plants, the company met the industry's expectation by providing them with optimal power supplies as X-ray, laser, nuclear, and other new devices were developed.
In recent years, needs for power supply equipment have become much wider. Some examples are the traveling wave tube power supply for microwave amplification used in satellite communication, the power supply for the ionbeam irradiation system used for studying materials for nuclear fusion reactors, and electrostatic precipitator to help clean the environment. Simultaneously, development of more compact and functional power supplies is in demand for the X-ray and laser equipment for medical application. At Origin, we are positively engaged in the tasks for meeting new needs while paying a great care to the product quality.

Semiconductor Devices

Symbol of Electronics Innovation
Origin aims to develop user-and ecology-friendly power devices, with high speed, high voltage, low loss and combination as main technological development goals.
Having taken up the challenge of realizing innovations in the field of semiconductors as core electronics technologies, Origin has made steady advancement in providing customers with power devices such as high-speed diodes, high-voltage diodes, MOSFETs, and silicon surge clampers essential for power related equipment.
To satisfy ever increasing social needs for noise reduction, ultra-soft recovery diodes (USRs) have been widely adopted for general industrial machinery such as uninterrupted power supplies, SW power supplies for communications equipment and motor inverters, and also for large industrial equipment such as steel-making and paper-manufacturing industries.
On the other hand, high-power MOSFETs using metal gates realize high speed switching at high frequencies, not attainable with IGBTs, for induction heater inverters and high-frequency power supplies for semiconductor production equipment.
In the field of portable equipment, Origin has developed a series of small, low-loss Schottky barrier diodes for personal computers, portable telephones, MDs and digital cameras, contributing to longer service life of batteries while attaining downsizing and less heat generation.
