Compared to conventional DC/DC converters in energy storage systems, the proposed converter achieves excellent operational performance, since it is equipped with an auxiliary ZVT cell with both small size and low power rating, it transmits only the soft switching energy of the switches, resulting in a lower converter cost and higher efficiency.
A dynamic mathematical model of the energy storage interface converter is given by (2) u b = e + (r b + s L b) i b i out − i dc = s C b u dc + G b (u dc − U N) where G b is the capacitance admittance and U N is the rated voltage of the DC bus.
With the proposed control scheme, the operation stability of the DC microgrid can be improved effectively.
