Outline of Final Research Achievements

Voltage equalizers for partial-shading compensation that can be composed of a few switches were developed for series-connected photovoltaic modules. Detailed operation analyses and experimental verifications were performed for two major topologies: multi-stacked buck-boost converters-based and resonant voltage multiplier-based voltage equalizers. The detailed operation analyses and experimental results revealed that both equalizers can effectively preclude negative impacts of partial shading and the efficacy of the developed voltage equalizers was demonstrated. Furthermore, the resonant voltage multiplier-based equalizer can be integrated with an ordinary PWM converter by sharing switches and a magnetic component, deriving a novel integrated converter. The integrated converter not only further reduces the circuit element count but also realizes the system-level simplification by integrating a PWM converter and voltage equalizer into a single unit.
