“…This pulsating input power oscillates at twice the grid frequency (2f ac ), leading to an inherent 2f ac ripple voltage across the DC bus. If not effectively mitigated by the rear-stage PSFB converter, this ripple voltage can have a significant negative impact on the operational lifespan of connected electrical equipment [10][11][12][13].…”

The inherent second harmonic power pulse in single-phase grid-connected rectifiers leads to a noticeable output voltage ripple and thus results in the degradation of the system. A novel second harmonic suppression control is introduced in this paper to address this issue. The key point of the proposed control lies in the real-time prediction of the phase-shifted full-bridge (PSFB) converter’s desired duty cycle through accurate PSFB converter modeling. By accurately predicting the ideal duty cycle, the proposed control facilitates a significant enhancement in the control loop’s gain specifically at the second harmonic frequency, thereby improving the overall system performance. To validate the theoretical analysis, a series of simulations and experiments were conducted. The results demonstrate the effectiveness of the proposed second harmonic suppression control in mitigating second harmonic output voltage ripple.

The design and development of a 550 W non‐isolated single‐phase two‐stage level‐1 bidirectional on‐board battery charger (OBC) for electric vehicles (EVs) have been discussed in this article, which is also capable of supplying the utility grid's reactive power needs. There are two stages in this topology. The first stage consists of a full bridge bidirectional AC to DC converter, and the second stage consists of a half‐bridge bidirectional DC to DC converter with enhanced vehicle‐to‐vehicle (V2V) capabilities for emergency roadside charging assistance scenarios. In an emergency, if there is not a charging station nearby and the battery is dead, EVs can use this feature to charge from other EVs. It can also work like a regular vehicle‐to‐grid (V2G) or grid‐to‐vehicle (G2V) system. The suggested charging topology has a maximum efficiency of 99.09%, a power factor of 0.99, and a total harmonic distortion (THD) of 6.31%. MATLAB/Simulink is used to develop and simulate the suggested EV charger, and simulation results are compared with the other on‐board chargers in the literature.
