Polarity, Inc.

Polarity, Inc. was founded in 1999 to meet the growing demand for innovative, reliable, and affordable high voltage power systems and solutions.

Our modern 10,000 sq ft facility in Rancho Cordova, CA is equipped with the tools necessary to perform power electronic, analog, and digital circuit design. It also has comprehensive thermal and mechanical design capabilities and the equipment necessary to perform complete product characterization, including environmental testing for temperature, altitude, vibration, and shock.

Polarity's designs can be found in many mission-critical applications. We serve the US military by providing high reliability power systems that operate in harsh airborne or shipboard environments. For commercial applications, most products initially developed for the military as scaled down, reducing cost without compromising ruggedness or reliability.
