Power transmission type performance test device

摘要

(57) Abstract Objective In the electric dynamometer performance test power transmission systemBeing, performance test under explosion torr cripple impressing possibilityIt does. Constitution As for reference signal wave generation circuit, reference signal wave between three phase circuitsIn order so to become imbalance, deformation. Or standard trustControlling the zero point of the number wave, direct current amount it is superimposed in the reference signal wave(Ripple mark A). This reference signal wave PWM modulation circuit PWMModulating, Drive the inverter. Output torr of induction motorThe ripple component is generated in ku. This torr cripple componentAs a pseudo component of the explosive torr cripple of the engine mitsuSuch as Shaun in the automobile, performance test of the power transmission system columnu.
