摘要：A PWM rectifier includes a main circuit unit which performs a power conversionon the basis of a PWM control signal, a DC voltage loop control unit which generates acurrent command, a current command restriction unit which sets, when an absolute value
of the current command exceeds a limit value, the limit value as a final current command,and otherwise sets the current command as the final current command, a DC voltageloop saturation determination unit which determines a saturation state when the finalcurrent command is set to the limit value and otherwise determines as a non-saturationstate, a DC voltage command calculation unit which changes the DC voltage commandinto a value obtained by adding an offset to a minimum or maximum value of the DCvoltage value, and a PWM control signal generation unit which generates the PWMcontrol signal from the final current command.
