Top power electronics threads on EDAboard.com – November
3V – 5V high current 150A power supply – I have been asked to generate a 100A RMS precise sinusoidal current. It will have negligible burden/load. Luckily I’ve done something very similar in the past where I used a LEM sensor, a dsPIC33, and an inductive load and a current-controlled PWM inverter based on a PI […]
