“…SS techniques are formed by the circuits called snubber cells, and basically provide zero voltage switching (ZVS) and/or zero current switching (ZCS) for semiconductor devices. This SS concept has been very popular for the last 20 years and continues to be so [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Resonant techniques are used generally to provide soft switching in soft switching inverters (SSI).…”

In this article, a new parallel resonant DC link (PRDCL) that provides soft switching (SS) and pulse width modulated (PWM) operation for inverters is presented. The new PRDCL ensures zero crossings for a time period, and at any time required for SS and PWM operation of the inverters, respectively.Moreover, the proposed PRDCL is realized by using only one auxiliary active switch, has a simple structure and ease of control, and operates under SS conditions. All switches in the soft switching inverters (SSI) equipped with the new PRDCL operate with soft switching, and are subjected to no additional voltage and current stresses. A detailed steady-state analysis of the proposed PRDCL is presented, and this theoretical analysis is verified by a prototype of a 250 V, 50 kHz and 1250 W circuit.

“…(iii) Reduced Voltage DC-Link: The concept of reduced voltage was proposed in [93], as shown in Figure 13. The loss calculation has also been specified [94]. This topology is composed of two additional resonant elements (Lh and Ch) integrated with the basic parallel resonant DC-link topology.…”

This paper comprehensively reviews the current status of multidisciplinary technologies in electric vehicles. Because the electric vehicle market will expand dramatically in the coming few years, research accomplishments in power electronics technology for electric vehicles will be highly attractive. Challenges in power electronics technology for driving electric vehicles, charging batteries, and circuit topologies are being explored. This paper aims primarily to address the practical issues of the future electric vehicles and help researchers obtain an overview of the latest techniques in electric vehicles, focusing on power electronics-based solutions for both current and future electric vehicle technologies. In this work, different medium-and high-voltage DC-AC inverter topologies are investigated and compared in terms of power losses and component requirements. Recent research on electric vehicle power converters is also discussed, with highlighting on soft-switching and multilevel inverters for electric vehicle motor drives. In this paper, a methodical overview and general classification of DC-AC power converters are presented. In specific topologies, drawbacks such as voltage stresses on active switches and control complications may occur, which can make them difficult for immediate commercialization. However, various modified circuit topologies have been recommended to overcome these drawbacks and enhance the system performance.
