摘要

本文研究了可再生能源系统中输入控制降压降压变换器的输入输出电压增益和效率分析。系统研究了连续导通和间断导通两种工作模式。在研究中，考虑了电感的寄生电阻，并通过储能或后级功率调节器固定直流链路输出电压。应控制输入电压以跟踪最大功率点。在系统中，CCM-DCM的边界条件与传统的输出控制变换器的边界条件完全不同。最后，给出了大量的仿真结果来比较降压变换器在电压增益和功率效率方面的差异。

Steady-state analysis of the buck converter for renewable energy systems

This paper investigates an input-output voltage gain and efficiency analysis of input-controlled step-down buck converter for renewable energy systems. The system investigates operation in two modes, continuous conduction mode and discontinuous conduction mode. In the research, the parasitic resistance of the inductor is considered, and also DC-link-output voltage is fixed by energy storage or by the post stage power conditioner. The input voltage should be controlled for tracking the maximum power point. In the system, the CCM-DCM boundary condition is totally different from that of an output-controlled converter for conventional. Finally, extensive simulation results are also presented to compare in voltage gain and power efficiency to buck converter.
