Totem-pole power factor correction (PFC) is a simple and highly efficient topology. It is being widely used in high-density and high-efficiency power supply design. However, engineers still face many design challenges, including PFC current reversing prevention at input voltage drop, lightning surge protection, current harmonic reduction, and ac crossover current spike … [Read more...] about Totem-Pole PFC Reliability and Performance Improvement With Advanced Controls

Cost-Effective Arduino-Based SPWM Control of an Inverter for Training
In this work, a cost-effective sine pulse-width modulation (SPWM) control of an inverter has been implemented using Arduino UNO microcontroller, which can be used with various power stages. The proposed model is focused on power electronics training or learning. It allows users to practice the control of an inverter without the need to be in a face-to-face laboratory. The … [Read more...] about Cost-Effective Arduino-Based SPWM Control of an Inverter for Training
