About VMI

VOLTAGE MULTIPLIERS INC. was incorporated in December 1980 to design, manufacture and market high voltage semiconductor products. VMI initially designed and produced high voltage multipliers. The addition of high voltage diode manufacturing capabilities led the way to expanding our facilities and product lines to include custom high voltage power supplies.

The nature of VMI’s business requires a high degree of engineering service and follow-up customer support. VMI’s products are custom designed for military, industrial, medical, aerospace and other high-reliability applications operating at the leading edge of known technology.

The general market for VMI products is semiconductor power conversion devices, assemblies and systems. VMI has developed some of the world’s fastest switching rectifiers, and our growing product line of custom high voltage power supplies is being utilized in various applications worldwide.

When you look for high voltage power supply designers, important things to consider include the company’s methods of design verification, prototype capability, design-for-manufacturability skills, the ability to transition from prototype to production scale, and standard and custom testing.

At VMI, we are committed to quality and service. We are here to assist you throughout the production process, from design development to production manufacturing. We offer extensive testing, design verification, production support and custom design services.

All of VMI’s products are made and 100 percent tested at our facility in Visalia, California, USA.
