Clearing the Foam: A guide to understanding reactive power
Struggling with explaining reactive power? So did I! But after writing this article, both of us can do it!
Gate drivers
Although in principle only a signal buffer, there are many design considerations and additional features that affects the performance of the gate driver. This article aims to cover the basics.
PWM Challenges Part 2 - Bearing Currents
Applying pulse trains to an electric motor comes with some interesting consequences. In this post, we take a closer look at currents arising inside the motor frame and how they flow about.

Teardown of a commercial motor drive
Let's have a look at how the power circuitry is implemented in a commercially available motor drive.
Circuit simulation with QUCS
Quite Universal Circuit Simulator(QUCS) is a open source SPICE based circuit simulator.
PWM Challenges - Part 1: Voltage reflections
Voltage reflections is a phenomenon where a propagating voltage pulse arrives at the load and returns back to the source due to high dV/dt. This post explains the theory behind it and how to handle it.
Transformer and inductor design
Transformers and inductors are important in all areas of electronics. Lets go over the basic operating principles, as well as some methods used when designing such components.
