“…However, if a single PSFB converter is used to step down the bus voltage from 400 V to 1 V, the planar transformer need to have a voltage transformation ratio more than 100 : 1 with switching frequency greater than 1 MHz, which is difficult to be realized with acceptable efficiency. Therefore, input series output parallel (ISOP) connected system containing several DC/DC converter modules was used as the power supply topology [4][5][6]. A six phase interleaved phase shift DC/DC converter switched at 280 kHz was selected.…”

“…As the two modules are input series and output parallel connected, then input current sharing and output voltage sharing is enforced and the following two equations are satisfied under any circumstances. Assuming the two modules having comparable efficiency [6]: (1) ( 2) where n 1 and n 2 are the turns ratio of each converter, D eff1 and D eff2 are the efficiency duty cycle of each converter, V C1 , V C2 , I L1 and I L2 are the input voltage and output current for each converter.…”

“…However, they require a tight voltage regulation to properly distribute load current, otherwise, it can potentially overload a converter [7]. Active sharing techniques have received more attention, e.g., master-slave [1], [4], [10], [11], circular chain [12]- [14], common-duty-ratio [15]- [17], and sensorless current mode [18] techniques. The goal is to share the load among different converters proportional to their current ratings or, equivalently, to equalize the per-unit currents, which is referred to as the proportional load sharing.…”

“…With identical converters, the master can produce the duty command and relay that to other converters [15]- [17], e.g., through RF transmission [10]. Despite simplicity, the common-duty-ratio is susceptible to converters' parameter or input voltage mismatch.…”
