Interleaved Pulse Width Modulation Based on Modified Carrier in Parallel Operation
An interleaved pulse width modulation (PWM) can be employed in a parallel operation of three-phase converters because the interleaved PWM increases the equivalent switching frequency and significantly enhances the output current harmonics.
