Pulsed Power Japan Laboratory Co., Ltd.

Top-level techniques for high-voltage pulse power sources in the world.

High-voltage pulse power sources are expected to be applied in many new industrial fields such as cancer treatment, nondestructive inspections for bridge structures, as well as research uses for accelerators and the like. Improved performance and miniaturization are extremely important development themes. We are organized as an enterprise specialized in this field. We are promoting commercialization of small, high-performance high-voltage pulse power sources by the complex combination of semiconductor switching techniques. Up until now, our products were unstable and short lived. We have, however, developed techniques for generating stable pulses of high voltage and large current at 1 million Hz or more for extended periods.


Other presentation

[Company strength]
(1) We promptly take up customers’ requests from the research network, and can make proposals based on the viewpoint of customers as technical consultants.
(2) We have the largest repertoire of techniques of Japanese enterprises. We can propose the optimum products for customers’ uses among many circuit structure types and usable part types.
(3) We have top-level techniques in the world for high-voltage pulse power sources.

[Business description]
High-voltage pulse power source are expected to be applied in many new industrial fields in addition to research uses for accelerators etc. The fields include cancer treatment, nondestructive inspections for bridge structures, electron-beam sterilization, semiconductor lithography, wastewater treatment, exhaust gas treatment and acceleration of engine ignition. Performance improvement and miniaturization of high-voltage pulse power sources are, therefore, extremely important development themes. The market of said power sources in Japan is too small for major electrical machine manufacturers, and special techniques are required. SMEs therefore cannot enter the market in the present situation. We were organized as an enterprise specialized in this field. We promote commercialization of small, high-performance high-voltage pulse power sources by the complex combination of semiconductor switching techniques.

Manufacture of electrical equipment

[Strength of products/technologies]
Vacuum tubes etc. could not withstand heavy usage with high-voltage pulse power sources due to the high voltage and large current and as a result, stability and repetition was low and life span was short. We have developed techniques for stably generating high voltage and large current of several hundred thousand volts and several thousand amperes, in pulses of 1 nanosecond, at 100Hz for extended periods. This has been realized by combining semiconductor devices on the market with our own unique circuit techniques. We have made further yearly improvements and developed this semiconductor switching technique in cooperation with domestic research institutions and also have advanced with developing applications. As a result, we have become a manufacture capable of serving as a specialist technical consultant.

[Representative's message]
We have marked our 6th anniversary, and our permeation to domestic main users has been advancing gradually. We have been gradually receiving inquiries from overseas by publicizing our results overseas at international conferences and through papers. We cannot, however, respond to overseas development partly because our system for employees in charge of such affairs has not grown sufficiently. We have also been restraining active development of sales channels so that received orders would not suddenly increase from domestic users as well. We will reinforce and educate the in-house personnel, strength our internal system, and further promote expansion of domestic and overseas sales channels.

[Company structure for market development/overseas expansion]
We have Japan’s best technical capabilities through close cooperation with domestic university laboratories for high-voltage pulse generating technology. We have built up a sales network for all new users including major enterprises and have done the same for research institutions. We have not yet fully worked on matters such as quality and environment including ISO standards, and this situation has hindered order intakes. We are making progress to obtain ISO 9001 certification within this fiscal year, as well as 14001 certification from the next fiscal year onward.
