The Power Factor Correction Circuit
Simulation and PFC Inductor Design with
SIMPLORER® and PExprt®
System engineercreates a design idea
Draw the schematic inSIMPLORER environment
Obtain the design parameters needed for magnetic components
Input into PExprt and get the optimized design
per designer’s option priorities
The Integrated Simulation and Design Tools:
SIMPLORER® and PExprt®
Send to the Prototype shop
Test and adjust parameters to achieve the specs
