RE-ADHESION CONTROL OF INVERTER ELECTRIC MOTOR VEHICLES

초록

This study was carried out re-adhesion control of inverter electric motor vehicles. The power converter is driven by dual converter and is kept a high power factor of power source. This system is havingz all the characteristic of voltage source converter by having a processing ability of regenerating power. This converter is able to convert a 300kw power, and is a DC power supply output a 1500V DC voltage for inverter driving. In theory, in order to prove analysis for adhesion system and re-adhesion condition, simulation conducts for each condition. During test of adhesion control, to be sure detect, analysis for phenomenon conducts in skid state. The test equipment is composed of traction motor, torque-meter, clutch, and inertia body of cylinder type"
