The experimental prototype with a switching frequency of 50 kHz, 300 V for the main battery, 48 V for the auxiliary battery, 24 V output voltage, and 300 W rated power is implemented to verify the theoretical analyses. The maximum efficiencies of the proposed TPC are 94.3% under 150 W, 96.6% under 60 W, 94.4% under 75 W, 94.4 % under 90 W, and 95% under 140 W at SISO-I, SISO- II, SISO-III, DISO, and SIDO mode, respectively. The efficiency curves of SISO-I, SISO-II, SISO- III, DISO and DISO stages are shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, respectively.
