Abstract :
In this paper, the control performances of the three phase SVPWM inverter according to the phase current measuring method are compared. For this comparison, the current measuring methods using a current transducer (CT) and a shunt resistor are adopted. Furthermore, in the case of three shunt resistors are connected between under the emitter of power switch and the dc-link ground for phase current measuring in the SVPWM inverter, the restriction is analyzed and the output voltage compensation method is proposed to fix these problem. The experimental result using 1.5kW lab-prototype set is presented for the performance verification.
