Research Abstract

A Photovoltaic generation system has recently attracted a special interest as an infinite and clean energy system. Photovoltaic modules have a maximum operating point, where the maximum power obtained. The voltage of each maximum operating point changes depending upon many conditions, the intensity of the sunlight, the temperature of the photovoltaic module and so on.
In order to obtain the maximum power from the photovoltaic modules, we have studied three types of converters as follows.
1) Zero-voltage-switching (ZVS) DC-DC converter.
A new type of ZVS converter is presented, which is connected with a battery and a photovoltaic module as DC sources. It consists of a buck-boost converter and a buck converter. A control circuit is achieved by only one sensor using an inductor current through a part of the buck-boost converter. Moreover, it is clarified that the condition of the maximum average current of the inductor coincides well with the point of the optimal generation of the photovoltaic module. The optimal tracking control is easily performed by using the average inductor current.
2) Generation control circuit for photovoltaic system.
A generation control circuit is presented to obtain the maximum power from photovoltaic modules. The circuit improves output power from series connected photovoltaic modules including shaded ones. It is confirmed that the total generation power can be increased by using this generation control circuit.
3) Resonant-type multi-level PWM Inverter.
A novel type of PWM inverter, a resonant-type five-level PWM inverter, is presented. The output waveform of this inverter has multiple levels of voltage by connecting two units of power source in series or parallel combination. The operation and cxperimental results in this inverter are examined. The circuit operation of this inverter, having very small switching losses, is described.
