 In this paper， the second harmonic in the dc link is analyzed in detail and a new load current compensation technique is proposed。The proposed technique replaces the second stage dc/dc converter with a bidirectional dc/dc converter connected in parallel with the load， and requires a secondary energy source， i.e., a small-size capacitor。The capacitor injects 180◦phase-shifted second harmonic current to the dc link. Thus， the dc-link capacitor can be reduced significantly as it is only sized for high-frequency ripples rather than being sized for low-frequency content。 The proposed method is generalized for resistive and battery loads with voltage- and current-source PFC circuits。
