“…High switching speed power electronic devices play an important role and are an integral part of any power electronic converter. The selection of these devices is application specific and depends on the various factors, which include maximum operating voltage, current, on-state resistance, rise time, fall time and cost, making the selection process complex [14].

Electric vehicle (EV) battery chargers operate from moderate switching frequency (MSF) to high switching frequency (HSF) to achieve high power density. To operate the HSF power electronic devices, the selection of gate drivers and its associated components is crucial. Laboratory developed gate driver circuits (GDCs) often fail to drive these HSF devices adequately due to noise vulnerability, PWM duty loss and common-mode currents. Further, at MSF and HSF ranges, the gateto-source terminals of the device are subjected to high voltages due to unwanted noise resulting in false turn-on of the switch leading to the converter failure. In this paper, firstly, an improved GDC and it's associated component selection criteria are proposed for HSF EV application. The proposed GDC is simple in structure with minor components; thus, it is cost-effective and highly reliable. Secondly, the proposed GDC is compared with the other commercially available competent GDCs. Power losses, cost and dynamic switching performance are the figures-of-merit for the quantitative assessment. From the comparison, it will be shown that the proposed GDC exhibits an overall superior performance among the popular GDCs. Finally, the distinctive features of the proposed GDC are experimentally validated for several test cases and the obtained results are presented.

“…Each power unit has its merits and demerits. Among these power units dc–dc converter stage is more popular as it matches the charger rating with the required battery power requirement [1, 2]. Besides, in on‐board chargers a galvanic isolation is required for protecting the system from double fault.…”

The DC/DC converter stage has a significant role in the on-board electric vehicle (EV) battery charger. This study proposes a zero voltage switching (ZVS) full-bridge DC/DC converter (FBDC) for efficient power conversion with minimal power loss. The simplified auxiliary circuit-based FBDC consolidate the modified pulse width modulation (MPWM) gating technique for DC/DC conversion stage according to battery profile of the EV. The proposed MPWM can minimise the conduction and switching losses in comparison to the previously proposed converter configuration using conventional phase shift modulation (PSM) gating technique. The size of auxiliary inductance required is reduced with MPWM in comparison to conventional FBDC auxiliary inductance with PSM gating technique. Design and implementation of proposed ZVS FBDC with MPWM are discussed for a 500 W, 80 kHz laboratory prototype and experimental results are presented to validate the design and performance of the proposed converter.
