Ray Ridley, Ridley Engineering

Here we’ll look at how a rugged and flexible control can be rapidly implemented using an 8-bit microcontroller with analog blocks. For many custom power supplies, this provides an optimum combination of noise immunity, high performance, short development time, and digital flexibility. Analog PWM control circu

Analyzing a tightly-coupled Sepic converter

Dr. Ray Ridley and Dr. Vatché Vorpérian, for Ridley Engineering

Here we’ll explore the analytical transfer function for the tightly-coupled Sepic converter. It is shown that the control-to-output function is just second-order, not fourth-order like the conventional Sepic converter [1]. The coupling capacitor of the converter has no effect on the control, and it can be ma
