STDES-7KWOBC 是一款車載充電器 (OBC) 參考設(shè)計(jì)，可通過(guò)家用交流電源插頭或私人/公共插座（交流充電站）為電動(dòng)汽車 (EV) 的電池充電。

參考設(shè)計(jì)嵌入了兩個(gè)部分：帶有 SiC 的交錯(cuò)圖騰柱 PFC 和基于 MDmesh DM6 超結(jié)功率 MOSFET 的雙電流隔離 LLC DC-DC ZVS 諧振轉(zhuǎn)換器。

電源平臺(tái)是一個(gè) 7 kW 模塊，能夠在輸出端提供恒定電流 (CC) 或恒定電壓 (CV)，可用作獨(dú)立 (1 PH+ N)、并聯(lián)或三相模式 (3Ph + N)，以達(dá)到 21 kW。
鋁基板上的底層絕緣金屬基板可實(shí)現(xiàn)非常有效的散熱、強(qiáng)制或液體冷卻。
組成參考設(shè)計(jì)的每個(gè)模塊都允許通過(guò)電線或母線連接在相同類型的模塊之間輕松互連，從而達(dá)到更高的輸出功率。
該參考設(shè)計(jì)的關(guān)鍵因素是效率和高功率密度，這得益于 SiC 和 SJ 功率 MOSFET、硅和 SiC 二極管、柵極驅(qū)動(dòng)器、SPC58NN84E7 功率架構(gòu)汽車級(jí)微控制器以及用于限制浪涌電流的 SCR 晶閘管。
STDES-7KWOBC 是專為性能評(píng)估而開發(fā)的全組裝套件，不對(duì)外出售。

The STDES-7KWOBC is an on-board charger (OBC) reference design which 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 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 on aluminum base plate enables very effective heat dissipation, forced 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 SPC58NN84E7 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.
