 Abstract – The performance of an isolated high voltage full bridge converter is improved using a voltage doubler. In a conventional high voltage full bridge converter, the diode of the transformer secondary voltage undergoes a voltage spike due to the leakage inductance of the transformer and the resonance occurring with the parasitic capacitance of the diode. In addition, in the phase shift control, conduction loss largely increases from the freewheeling mode because of the circulating current. The efficiency of the converter is thus reduced. However, in the proposed converter, the high voltage dual converter consists of a voltage doubler because the circulating current of the converter is reduced to increase efficiency. On the other hand, in the proposed converter, an input current is distributed when using parallel input / serial output and the output voltage can be doubled. However, the voltages in the 2 serial DC links might be unbalanced due to line impedance, passive and active components impedance, and sensor error. Considering these problems, DC injection is performed due to the complementary operations of half bridge inverters as well as the disadvantage of the unbalance in the DC link. Therefore, the serial output of the converter needs to control the balance of the algorithm. In this paper, the performance of the conventional converter is improved and a balance control algorithm is proposed for the proposed converter. Also, the system of the 1.5[kW] PCS is verified through an experiment examining the operation and stability.

 (Abstract)
As fossil fuels become depleted and environmental problems arise, the renewable energy is being proposed as a solution to these problems. Among the renewable energy sources, photovoltaic is attracting much attention as an infinite energy source. In order to expand the PV-based infrastructure, the increase in facility supply has not been large due to economical reasons, As the unit price has been lowering and it is expected to be continued to decline in the future, the spread of solar power generation is expected to expand. In this expectation, the PV-related household ESS field is also a hot issue. The household battery pack usually has a voltage of 380 ~ 550V. When the system is constructed by replacing it with 48V, which is relatively low voltage, some features and advantages. In this paper, we discuss the low-voltage system and simulate using the PSIM to verify the validity of the applied system according to the characteristics of the proposed system. And Proto-type has made for experiment and has proved the validity of the proposed system.
