Based on the theoretical analysis, a small-signal model of the DC/DC converter is built to calculate the input current ripple mathematically. To reduce the 100-Hz current ripple, the PIDR control is proposed. To decrease the quantized current ripple, the HRPWM technology is applied and thus the accumulated quantized error is minimized.
This paper proposes a DC-link ripple current minimization strategy to enhance the reliability of three-level voltage source inverters (3L-VSIs). The largest current among the three-phase currents flows through DC-link capacitors when a conventional space vector pulse width modulation (SVPWM) is applied to the 3L-VSIs.
Finally, a 2-kW bidirectional DC/DC converter prototype is built. According to the experiments, the current ripple is reduced dramatically by 81.5% at full load with the proposed current ripple reduction methods. 1. Introduction Various types of new energy can be utilized thanks to the micro grid .
