“…Four relevant examples of the implementation of state-of-the-art DAB converters with similar power ratings (100-500 kW) and voltage levels (i.e., 400-800 V) are available in the literature [26][27][28][29]. It is interesting to notice, for all the published DAB converters at this power ratings with state-of-the-art performance, the selected technology in SiC FET modules.…”

“…It is interesting to notice, for all the published DAB converters at this power ratings with state-of-the-art performance, the selected technology in SiC FET modules. The designs of [26,28] are 100 kW converters at 20 kHz and 16 kHz switching frequency, respectively; the converter in [27] delivers 200 kW at 50 kHz, whereas the one in [29] is a 500 kW DAB converter at 20 kHz. In the design described in this paper, high power (350 kW) and high switching frequency (50 KHz) are combined in the same product.…”

In this paper, the design and implementation of a DC/DC converter for automotive component testing with state-of-the art performance is described. The converter is the core of a battery emulator for the characterization and development of automotive batteries, electronic chargers, traction inverters, DC-DC converters, E-motors and E-axles. Cutting edge performance, flexibility and compactness are obtained by exploiting 1200-V SiC modules, high switching frequency, planar transformer technology, suitable topology solutions and fast digital control strategies. The implemented system is a liquid-cooled, bidirectional converter with galvanic isolation capable of 350 kW continuous output power, output voltage range 48–1000 V, continuous output current up to 800 A (1600 A peak), voltage/current ramp-up time below 10/2 ms and 0.1% current/voltage accuracy. The entire instrument is implemented in a standard full-height 19-inch rack cabinet.
