Ridley Engineering

Ridley Engineering

Ridley Engineering is a specialized test and measurement company focused on power supply design and analysis tools. Founded by Dr. Ray Ridley, the company is best known for the AP310 frequency response analyzer — an instrument designed specifically for measuring loop gain, phase margin, and impedance in switching power supplies and DC-DC converters. The AP310 enables power electronics engineers to verify control loop stability and characterize the dynamic behavior of power conversion circuits through Bode plot analysis.

Ridley Engineering also provides simulation software and educational resources for switching power supply design, making it a focused resource for engineers working on SMPS, inverters, and DC power systems who require specialized loop analysis instrumentation.
