APPLICATION OF VIRTUAL IMPEDANCE TO SUPPRESS DEAD-TIME EFFECT IN CURRENT-CONTROLLED PWM INVERTERS
Dead-time is necessary in a PWM inverter to avoid short-corcuiting the DC source through the semiconductor switches. Due to the momentary loss of voltage control during dead-time, the output voltage becomes distorted, particularly with low-order harmonics. In motor applications, current harmonics...
