A freewheeling MOSFET is connected in parallel with the inductor in a switched DC/DC converter. When the freewheeling MOSFET is turned on during the switching operation of the converter, while the low-side and energy transfer MOSFETs are turned off, the inductor current circulates or "free...
This paper describes the design, construction, and testing of a 750-V 100-kW 20-kHz bidirectional isolated dual-active-bridge dc-dc converter using four 1.2-kV 400-A SiC-MOSFET/SBD dual modules. The maximum conversion efficiency from the dc-input to the dc-output terminals is accurately meas...
直流电压变换器(DC-DC Converter)是一种将直流电能转换为另一种直流电能的电力电子设备。根据电压等级变换关系,可以分为升压电源和降压电源两类;根据输入输出关系,可以分为隔离电源和无隔离电源两类;根据工作原理,还可以分为电荷泵和电感储能DC/DC转换器两类。 主要技术指标 输入电压范围:指变换器能够接受的输入电压...
DC-DC开关电源,即直流直流变换器(Direct Current-Direct Current Converter, DCDC),是一种能将直流电压从一个等级转换为另一个等级的电子设备。针对DC750V转DC600V、750V或800V的需求,以下是对DC-DC开关电源的详细解析: 一、工作原理 DCDC电源的核心在于通过电力电子器件(如MOSFET、IGBT等)的开关作用,结合电感、...
We propose an autonomous DC microgrid system in which a three-way isolated DC/DC converter is used as a power routing unit. As the unit in the system operates with various power flow patterns, a highly efficient system cannot be easily designed unless the dependence of the unit's overall ...
This converter comprises: a transformer with two primaries (P1, P2); a voltage source (Vi n) one of the terminals of which is linked to the midpoint; and two switches (T1, T2), mounted in series between the other terminal of the source and one primary, which exhibit a stray capacitanc...
