1. The Power Factor Correction Circuit Simulation and PFC Inductor Design with SIMPLORER® and PExprt®
SIMPLORER´s software structure
Each language (domain) is handled on a specific simulator.
Circuit Simulator
the circuit simulator works using similar algorithms than SPICE but it is not SPICE source code based.
The algorithms were optimized for very stiff differential equation systems and therefore can handle frequently switching systems easily
SIMPLORER´s circuit simulator is extremely stable and has usually no convergency problems
Simulation speed can be up to 10 times faster than SPICE, depending on the modeling
Block Diagram Simulator
Different implementation than Matlab/Simulink.
