Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

The purpose of this article is to walk through the steps of implementing a ripple injection circuit for constant on-time POLs. It covers how to connect the circuit and then how to calculate the values ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

While most readers are knowledgeable about voltage doublers, here is a discussion about how to use them in unusual ways to enhance power supply circuits that might be otherwise limited in features.

Peter Green explains advantages of LED drivers based on the flyback power-supply topology: They're inexpensive; they provide an isolated output that complies with UL safety requirements; they make it ...

And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...
