Topology and Control Investigation of Soft-Switching DC-DC Converters for DC Transformer (DCX) Applications
… data center power supplies, and solid-state transformer (SST) systems, the fixed-ratio isolated DC-DC converter, namely the DC transformer (DCX), has gained significant popularity. Similar to the passive AC transformer, DCX can bidirectionally convey DC power with very high efficiency. Due to …

Magnetic and Thermal Design of Litzwire 500 kHz Highpower Planar Transformers with Converging Cooling Duct for “dc Transformer” Resonant Converter Applications
… the design and analysis of two Litz wire transformers for a 500 kHz, 18 kW inputparallel outputseries partial power processing converter (IPOS PPP). Because the two power paths in the IPOS PPP operate as “dc transformers” (DCX), both transformers are designed with the goal of leakage …

Variable Ratio Matrix Transformer based LLC Converter for Two-Stage Low-Voltage DC-DC Converter Efficiency Improvement
The low-voltage dc-dc converter (LDC) in electrical vehicles (EVs) is to convert high dc voltage (270V~430V) from traction battery to low dc voltage (12.5V~15.5V) for the vehicle auxiliary systems. Galvanic isolation is required in the LDC due to safety considerations. Three challenges exist in the …

Current Sharing Method for DC-DC Transformers
… output converter. It can be replaced by a dc-dc transformer (DCX), which is a semi-regulated or unregulated, single output dc-dc converter. A DCX can be made using a modular design to simplify expansion of the system capacity. To realize this concept, the DCX block must have a current …
