Consequently, the pulsating current flowing from the inverter to the dc source can be effectively reduced . This, in turn, mitigates the dc-link voltage ripple, ensuring a relatively stable dc-link voltage under inverter switching actions .
The DC-link voltage ripple of Si-IGBT based inverter under the modulation method of SVPWM is evaluated in and . For a conventional IGBT based inverter, because of the low switching frequency, bulky DC-link capacitor is necessary.
Therefore, a thorough analysis of the dc-link current and voltage ripples on the capacitor in a five-phase inverter is essential for both optimal capacitor design and accurate performance evaluation. For the capacitor, high-frequency dc-link current ripple is introduced due to the PWM of the inverter .
In this paper, a proposed method is developed by consider-ing the inverter antiparallel diode reverse recovery to analyze the dc-link current and voltage ripples, and the impact of diode reverse recovery on the current and voltage ripples is evalu-ated.
