This paper proposes a family of integrated multiple output isolated dc–dc converters, in which switches are hybrid utilized. Compared with the conventional separate $N$ -output isolated converter, which employs $2N$ primary switches, only $N$ +1 switches are required in the primary side of proposed converters to independently regulate $N$ secondary output voltages. Therefore, the number of switches...
Due to the challenge of energy demand, renewable energy sources are introduced to our daily life in order to satisfy the energy demand and reduce the emission of greenhouse gas. But the increasing penetration of renewable energy sources causes obvious impact on the conventional power systems especially the control strategies. In order to solve the problem, microgrid is introduced, which usually consists...
Nowadays, renewable energy technologies, such as solar power and wind power, are trend to replace conventional energy resources. In the meantime, DC Microgrid is becoming popular in distribution systems due to the better compatibility and simpler system control strategy. This paper presents a hierarchical coordinated control strategy for DC Microgrid with wind turbine and photovoltaic array under...
This paper presents the differential power processing (DPP) with isolated-port of submodule integrated converters (subMICs) in order to improve energy capture in photovoltaic (PV) power system. The nearly voltage equalization control and flyback subMICs are selected, which are working in discontinuous conduction mode (DCM) with fixed duty ratio 0.5. The simulation is built on Matlab/Simulink. The...
