“…However the switch in RDCL converter suffers from high voltage stress (about 2.5 times the output voltage). The active clamped RDCL in [7], [9]- [11], has a low voltage stress (about 1.3-1.4 times the output voltage). The simplified circuit of the ACRDCL Converter is shown in Fig.…”

A zero voltage switching space vector modulation (ZVS-SVM) controlled three-phase boost rectifier is proposed. A branch composed of one active switch, one resonant inductor and one clamping capacitor is added to the six-switch boost rectifier. In addition, a ZVS-SVM for the rectifier is proposed. It can effectively suppress the reverse recovery process of the bridge switch anti-parallel diodes. All the switches are turned on under zero voltage condition, thus the switching loss is reduced, and electromagnetic interence can be lowered. The switching frequency of the rectifier is fixed. The auxiliary switch works at the same frequency with other switch. All the switches in the rectifier have lower voltage stress. A digital signal processor controlled 4-kW prototype is built to verify the theory. Index Terms-Electromagnetic interference (EMI), power factor correction (PFC), zero voltage switching space vector modulation (ZVS-SVM).

“…For the DC-side auxiliary circuit, the auxiliary circuit is placed between the DC bus and the main switches, and only one set of auxiliary circuits is needed. However, different auxiliary circuit structures will result in varying voltage stresses on the main switches that are approximately 1 to 3 times the DC link voltage in the rectifiers [4][5][6][7][8] and inverters [2,[9][10][11][12][13][14][15][16][17][18][19][20][21]. Active clamping ZVS rectifiers [7,8] and ZVS inverters [2,[17][18][19][20][21] with low voltage stress (about 1.01~1.1 times the DC link voltage) were proposed.…”

In this paper, a bidirectional grid-tied ZVS three-phase converter is proposed. The circuit operation principle in both the rectifier and inverter modes was analyzed. The proposed topology could achieve zero-voltage switching in the six main switches and the auxiliary switch both in the rectifier mode and inverter mode. In addition, the reverse recovery current of body diodes in the main switches was also suppressed. Furthermore, in order to realize the ZVS control scheme under the grid-tied bidirectional power flow condition and reduce the number of switchings, a modified carrier-based discontinuous PWM was proposed to fit the bidirectional switching sequence. Finally, a 3 kW prototype was constructed. Some simulation and experimental results are presented to verify the validity of the proposed circuit topology and PWM control scheme.

“…The DC-side soft-switching technique usually has one simple auxiliary circuit installed in the DC-side. A well-known inverter with the DC-side soft-switching technique is the DC resonate link inverter or active clamping DC resonate link inverter [5][6][7][8]. It can realize soft-switching for all switches.…”

Power electronic conversion plays an important role in flexible AC or DC transmission and distribution systems, integration of renewable energy resources, and energy storage systems to enhance efficiency, controllability, stability, and reliability of the grid. The efficiency and reliability of power electronic conversion are critical to power system applications. One way to enhance the efficiency and reliability of power electronic conversion is soft-switching technology. This paper introduces a generic zero-voltage-switching (ZVS) technique based on silicon carbide (SiC) power device. Using the proposed ZVS technique, all semiconductor switching devices in a power converter can realize ZVS operations. Next, the applications of the ZVS technique in different power electronic conversion systems such as photovoltaic inverters, wind power systems, energy storage systems and flexible AC transmission system devices are discussed. Finally, as an example, the operation performance and efficiency improvement of a SiC metal-oxide-semiconductor field-effect transistor (MOSFET) ZVS back-to-back converter are discussed.
