Electronic equipment and power supplies without any active or passive power factor correction (PFC) circuits have an input current waveform which has a poor power factor and high harmonic distortion.
Ideally switch-mode power supplies would behave like mathematical models. But since they don’t you need to perform thorough characterization and troubleshooting. Fortunately, modern oscilloscopes are ...
How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...
