产品概述
描述
The STDES-7KWOBC is an on-board charger (OBC) reference design that allows charging the battery of electric vehicles (EV) through your home AC mains plug or a private/public outlet (AC charging station).
The reference design embeds two sections: an interleaved totem pole PFC with SiC and a dual galvanic isolated full bridge LLC DC-DC ZVS resonant converter, based on MDmesh DM6 super-junction power MOSFETs.
The power platform is a 7 kW module able to deliver a constant current (CC) or constant voltage (CV) on the output to be used as standalone (1 PH+ N), in parallel or in 3-phase mode (3Ph + N) to reach 21 kW.
The underlying insulated metal substrate (IMS) on aluminum base plate enables very effective heat dissipation, forced air or liquid cooling.
Each module composing the reference design allows an easy interconnection among modules of the same type through wires or bus bar connection, reaching a higher output power.
This reference design key factor is the efficiency and high-power density gained thanks to SiC and SJ power MOSFETs, silicon and SiC diodes, gate drivers, the SPC58NN84E7RMHBR power architecture automotive-grade microcontroller, and SCR thyristors for inrush current limitation.
The STDES-7KWOBC is a fully assembled kit developed for performance evaluation only, not available for sale.
