30kW Discrete Interleaved LLC DC-DC Converter CRD30DD12N-K

DOCUMENTATION ONLY, NO HARDWARE

The 30kW 3 phase interleaved LLC DCDC converter (CRD30DD12N-K) targets high-power-density, high-efficiency fast charger applications and features Wolfspeed’s discrete 1200V C3M Silicon Carbide MOSFETs (C3M0040120K) and 650V C6D Silicon Carbide Schottky Diodes (C6D20065D and C6D10065A).

A 3-phase interleaved LLC topology is implemented to provide low input current ripple and high efficiency for EV high power fast charger. Discrete power devices offer cost effective and common package solutions. The reference design accommodates all different levels of EV charging with a wide output voltage range of 200V-1000V while maintaining a high power density of 6.5kW/L and higher than 98% peak efficiency. The adaptive control operates over a 130kHz-250kHz switching frequency range to maintain optimal control over all operating conditions.
