What we do can be summarized in five categories:


Our five-day hands-on laboratory workshops have been the premier education source for design engineers in industry for over 20 years. We have been teaching the subject of power supply design for over 30 years. Our permanent design facility is located in Camarillo, California.


Created in 1991 by Dr. Ray Ridley, RidleyWorks® remains the industry's leading software program for designing switching power supplies in both commercial and military applications.


Dr. Ridley's book, POWER SUPPLY DESIGN, VOLUME 1: CONTROL, is the first in a series of books designed to explain power supply design to all levels of designers from beginning to experienced engineers. You will also find numerous control and magnetics publications in our Design Center. 


To complete your design process with accurate and dependable measurements, we sell the AP310 Frequency Response Analyzer from AP Instruments and the RidleyBox® test and measurement system with an integrated frequency response analyzer, oscilloscope and on-board computer. A full range of accessories are also developed inhouse for both instruments.


When you simply need help from an expert during the design process, you can rely on our team of consultants.
