Demands of an advancing market
With electric vehicles (EVs) becoming viable alternatives to traditional internal combustion engine vehicles in some markets, the demand for DC EV charging infrastructure is growing. Currently, this is especially true in China where EVs have gained momentum within the rapidly expanding middle class. The United States is expected to follow soon.
For these markets to accommodate EVs on a larger scale, drivers must be able to charge quickly. DC charging stations are an attractive choice because they allow for much faster charging than a standard AC EV charging pile, which many EV owners have at home. Today, a DC charging pile with 120kW can put a 100km charge on an EV in around in just 10-12 minutes. As both, fast charging and battery technologies improve the charging time will drop even further.
Today, DC EV chargers are becoming increasingly powerful and complex systems. They must fit into small spaces while also meeting high demands in terms of performance – a lineup that can quickly lead to a troublesome thermal situation. A high-performance charger could potentially overheat if not adequately cooled, a worst-case scenario designers avoid at all costs. That’s why energy-efficiency is the key to compact DC EV charger designs; up to 10 kW per liter is possible.

This ZVS phase-shift full-bridge evaluation board represents the newly developed ZVS DC-DC converter for telecom rectifiers with an output voltage from 45 to 56VDC and an output power of 2kW. This converter works with an input voltage between 350 and 420VDC (typical 385VDC) and a switching frequency of 100kHz on the primary side.
The EVAL_800W_ZVS_FB_CFD7 is a high performance example with a complete Infineon solution. The board includes high voltage and low voltage power MOSFETs, controllers and drivers, demonstrating a very effective way to design the high voltage DC-DC stage of a server or industrial SMPS, fulfilling the highest standard of efficiency and reliability.
