Performance comparison of input current ripple reduction methods in UPS applications with hybrid PEM fuel cell/supercapacitor power sources
We conducted a comparative study on different input current ripple reduction approaches in UPS system. SCs, LC filter, and an active clamp circuit were employed to reduce the input current ripples. Input current ripple generation and performance were analyzed and modeled in the PEMFC. Experiments were conducted to prove the effectiveness and feasibility of the different current ripple reduction methods.
