摘要：

In order to maximize the solar energy harvesting capabilities, power converters for photovoltaic (PV) systems have to be designed for high efficiency, accurate maximum power point tracking (MPPT), and voltage/current performance. When many converters are used in distributed PV systems, power density also becomes an important factor since it allows for simpler system integration. In this paper, a high-power-density string-level MPPT dc-dc converter suitable for distributed medium- to large-scale PV installations is presented. A simple partial power processing topology that is implemented exclusively with silicon carbide devices provides high efficiency and high power density. A 3.5-kW, 100-kHz converter is designed and tested to verify the proposed methods.
