“…While the low-frequency DC current ripple is often presumed to damage voltage sources such as lithium-ion batteries and fuel cells, recent research indicates that lowfrequency ripples (ranging from 100 Hz to 1 kHz) has no adverse aging effect on lithium-ion batteries (LiFePO 4 and NMC/graphite prismatic) [24,25]. However, current ripples below 10 Hz can lead to an increase in capacitor impedance and result in capacitance fade [26,27], though its significance in motor drive applications is diminished due to the relatively higher electrical speed of the motor drive.…”

In a multi-source permanent magnet synchronous motor (PMSM) drive, three distinct winding structures can be implemented: multi-sector, multi-three-phase, and highly coupled. However, due to variations in the magnetic coupling between windings, their low-frequency DC-link current ripple components differ. This paper presents a method to identify the phenomena associated with each low-frequency harmonic content. Three analytical models are developed for the DC current ripple induced by unbalanced winding, counter-electromotive force (back-EMF) harmonics and aliasing effects, respectively, with the results validated through simulations. Experimental validation is conducted for highly coupled winding drives, demonstrating agreement with the analytical models and simulations. The maximum DC current ripple ratio found in the analytical model, the simulation and the experiments is less than 15%, which is deemed acceptable for motor drive applications.

However, the electrolytic capacitors may limit the life-time, and increases the circuit volume (7) . In contrast, active power decoupling, which uses passive components with active switches, circuits have been proposed in order to solve this problem (8)- (15) .…”

This paper proposes a novel active power decoupling circuit that is integrated with an interleaved boost converter for isolated DC to single-phase AC conversion applications. The proposed isolated converter consists of two full-bridge inverters with a coupled inductor, a small buffer capacitor for active power decoupling, and a diode rectifier. Further, the proposed isolated converter is controlled for active power decoupling and DC to single-phase AC power conversion independently by the coupling inductor and common-mode operation of the interleaved boost converter, respectively. This paper presents the control method of the proposed converter and design criteria of the passive components. In addition, the performance of the proposed isolated converter is demonstrated by the experimental results in order to confirm the validity of the proposed method. As the experimental results, the second-order harmonic due to the doubleline frequency power ripple is reduced by 84.5% owing to the active power decoupling capability. Finally, a maximum efficiency of 94.5% is obtained using the proposed converter.
