PMP41144
具有平面变压器的 IGBT 和 SiC 栅极驱动辅助 PSU 参考设计
PMP41144
概述
This reference design introduces a tiny auxiliary power supply unit (PSU) used to supply automotive insulated-gate bipolar transistor (IGBT) or automotive silicon carbide (SiC) drive. The isolated outputs support three gate controls, each supplied with 21.2V, 2W output. This design uses the planar transformer to reduce the board height and cost. The LM25184-Q1 controller supports primary-side regulation by controlling the flyback voltage from secondary side. There is no need for an additional auxiliary winding. The board maximum efficiency is 89.2%. The design uses six PCB layers, and the temperature rise is 16°C with full load 6W.
