INVERTER SIMULATOR AND MOTOR SIMULATOR

PROBLEM TO BE SOLVED: To provide an inverter simulator capable of precisely calculating a three-phase output voltage of an inverter regardless of motor control mode, without the need for modification of a motor control device. SOLUTION: An inverter simulator simulates the inverter that supplies a three-phase power to a motor based on the signal from a motor control device. It includes a gate signal detecting means for detecting the state of gate signals from the motor control device, and a three-phase output voltage calculating means for calculating a three-phase output voltage based on the state of gate signals at a specified process cycle detected by the gate signal detecting means and a carrier cycle of the gate signals. The three-phase output voltage calculating means calculates a three-phase output voltage based on the state of gate signals at a plurality of process cycles, if the carrier cycle is longer than the process cycle.
