摘要

提出了一种电容耦合模块化DC-DC电力电子变压器(DCPET)。提出的DCPET由电容耦合无规LLC谐振变换器模块组成;这些模块以串并联方式连接。电容耦合拓扑被认为有望开发出高效的高功率密度变换器模块，并且这些模块的串并联可以顺利实现dcpet的各种电压比。采用gan - fet的48 V-48 V、450 W电容耦合LLC变换器模块的试验设计已被证明，并有可能达到99%，15 W/cm3。此外，还演示了使用8个98.8%，15 W/cm3的转换器模块的48 V-384 V DCPET，并验证了所提出拓扑的可行性。所提出的DCPET克服了孤立变换器的效率和输出功率密度之间的停滞关系，所提出的拓扑结构有助于电力电子设备的普及，以实现电力的经济利用。

99%, 15W/cm3 Capacitively Coupled Modular DCPET for Low-Voltage DC Power Supply Systems

A capacitively coupled modular DC-DC power electronic transformer (DCPET) has been proposed. The proposed DCPET consists of capacitively coupled unregulated LLC resonant converter modules; these modules are connected in series-parallel combinations. The capacitive coupling topology is considered to be promising to develop highly efficient high-power-density converter modules, and the series-parallel connection of these modules smoothly achieves various voltage ratios of DCPETs. A trial design for a 48 V-48 V, 450 W capacitively coupled LLC converter module using GaN-FETs has been demonstrated, and the potential to achieve 99%, 15 W/cm3 has been confirmed. Moreover, the 48 V-384 V DCPET using eight 98.8%, 15 W/cm3 converter modules has been demonstrated, and the feasibility of the proposed topology has been verified. The proposed DCPET overcomes the stagnant relationship between the efficiency and the output power density of isolated converters, and the proposed topology contributes to the prevalence of power electronics equipment for the economical use of electric power.
