The study presented here deals with an improved PFC stage under consideration of adapted boost inductor and capacitance at the drain node of the MOSFET. The detailed overall analysis allows to optimize a standard worldwide mains design. Additionally, the benefits of narrowing the input voltage r...
After the evaluation of Tj is done with all the losses, it's possible to update formula 2.8 and start the iterative process. In circuits like power factor correction (PFC) or motor drives where the envelope of modulation is sinusoidal, 10 ms or similar, it's important at the end of the...
