22kW BI-DIRECTIONAL ACTIVE FRONT END
This reference design demonstrates the application of Wolfspeed’s 1200V C3M™ Silicon Carbide MOSFETS to create a 22kW three phase bidirectional active front end (AFE) converter for electric vehicle (EV) on-board charger (OBC); DC fast charging; and other industrial applications such as energy storage systems and three phase PFC power supplies. This design operates as a standalone AC/ DC converter and is compatible with both single-phase and three-phase inputs. It has two operating modes: power factor correction (PFC) mode and inverter mode. In both modes, the DC bus voltage is flexible to demonstrate operation under a range of conditions. The use of 1200V C3M 32mOhm Silicon Carbide MOSFETs in a TO-247-4 package provides the best figure of merit (FOM) and reduces switching loss and cross talk.
6.6 kW HIGH POWER DENSITY BI-DIRECTIONAL ON-BOARD CHARGER
The 6.6 kW Bi-Directional On-Board Charger (OBC) targets high-power-density, high-efficiency on-board charger applications and features Wolfspeed’s new 650 V E-Series Silicon Carbide MOSFETS. The E3M0060065D/K are automotive qualified and PAPP capable and come in a 60m0, TO-247 package with the availability of a kelvin source pin.
In this high density OBC, all Silicon Carbide MOSFETs are mounted on a tooled AL heat sink, with all magnetics potted internally.
