INVERTER SIMULATION DEVICE, INVERTER SIMULATION PROGRAM, AND INVERTER DESIGN METHOD

摘要

PPROBLEM TO BE SOLVED: To shorten simulation time in design of an inverter. PSOLUTION: This inverter simulation device is provided with: an input data generation part 130 which generates input data from an electric circuit model and a device model; a solver part 140 which executes simulation using the input data; and an output editing part 150 which edits and outputs simulation results, wherein static characteristic broken line approximation circuit calculation part 141 of the solver part 140 performs a circuit calculation by approximating static characteristics of an IGBT, a MOSFET and a diode by broken lines.
