In three-level T-type NPC PFC converters, the conventional two-levelvoltage source converter (VSC) topologyis extended with an active, bi-directional switch to the DC link midpoint (see Figure 5). For 800 V DC link voltages, 1,200 V IGBTs/diodes would normally...
The soft switched PWM ZVS full bridge DC to DC converter and push-pull type LLC series resonant converter are compared for use in low output voltage power supply applications. It is shown that push-pull type LLC series resonant converter takes on the desirable characteristics of the conventional...

This is achieved with the DC-link voltage being clamped at the source voltage V, using minimum additional components. It requires only two additional switches compared to the conventional PWM converter. Moreover, the control circuit is not called upon to control the inductor current, as it is ...

In order to overcome these drawbacks, an improved ZVS three-level converter using passive auxiliary net is proposed in this paper. 针对典型的ZVS复合式全桥三电平变换器存在滞后桥臂实现零电压负载范围窄、变压器二次电压过冲大的缺点,提出了一种采用无源辅助网络的改进型拓扑。 2. An auxiliary net, whi...
This paper presents a new soft-switched, current-driven full-bridge converter. A simple snubber is used in order to get ZVS for all the main switches. The soft-switching realization is independent of the load. The snubber is placed in parallel with the bridge. All the resonant circuit energy...
