Idea for Design presents an algorithm for handheld calculators that gives a better approximation of of ripple voltages from a simple rectifier and cap. The standard practice for calculating the ripple ...

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 ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...
