This paper studies extremely high-precision efficiency measurement by building a back-to-back (BTB) system with a high-power DC-DC converter in order to realize a 100 kW high efficiency energy conversion system (HEECS) chopper with 99.5% efficiency. The newly proposed water-cooled 2-phase HEECS BTB chopper system achieves a reduction in input power and enables highly precise measurement of a high-power DC-DC converter with an extremely high efficiency of 99.5%.

“…A bi-directional isolated DC-DC converter is used as the battery interface system. A dual active bridge (DAB) converter has been studied actively as a bi-directional isolated DC-DC converter [1][2][3]. The DAB converter obtains the high efficiency and the high power density because zero voltage switching (ZVS) is achieved during the dead-time using an additional capacitor or a parasitic capacitance of the switching devices [4].…”

This paper discusses a Dual Active Bridge (DAB) DC-DC converter utilizing to three-level flying capacitor topology for a battery conversion system. With applying to a multi-level topology, the voltage stress is reduced in all switches. In addition, the low order harmonic components are reduced due to five-level waveform. In a two-level DAB converter, the efficiency becomes low when the input voltage is not closed to the nominal voltage. In order to improve the efficiency at the input voltage fluctuation, this paper also proposes the operation mode of the three-level DAB converter at the input voltage fluctuation. The output voltage waveform of the inverter is determined by the relationship among the efficiency of the two modes which are so called the full-bridge mode and the half-bridge mode. In this paper, the changing point between the half-bridge and the full-bridge mode is derived using the loss calculation. In the simulation, the ZVS range and the inductor current are compared with the two-level and the three-level inverter. It is confirmed that the ZVS range is extended by 60%. In addition, the fundamental operation of the proposed DAB converter is confirmed by the experimental results.I.

“…One type of bidirectional isolated DC-DC converter is the dual active bridge converter (DAB converter) (2) (3) . A feature of DAB converters is that they can reduce switching loss by zero voltage switching (ZVS), which should enable downsizing of the magnetic material and thus of the device, by high frequency driving.…”
