We have made a basic research on a small-sized, light-weight power conditioner possible to unify with solar battery panel, aiming at development and popularization of easily available, safe, small-sized, light- weight, inexpensive photovoltaic generation systems feasible for installation in a sense of awning.1. A basic circuit of resonant-type converter, which is heart of the power conditioner, was prototyped using power MOSFETs. Conditions for the soft-switching (zero voltage switching) operation under the output voltage control of the converter conbining the pulse width control and frequency control were found.2. It was clarified by simulations that the output current waveform of the converter was distorted considerably in the case co small output AC filter if the converter had no ability of bidirectional power conversion.3. Guidelines on the design method of the transformer and coils considering their losses within several tens kHz to several MHz and he reduction method of their los … More ses were obtained. A guideline to unify the resonant coils and transformer was also obtained.4. In order to examine the operatioal characteristics of the photovoltaic generation systems under the specific conditions, a simulation circuit to simulate the characteristics was prototyped. As a result, combining it with a solar model to simulate the variation of the solar power, it will be possible to evaluate the performance of the photovoltaic generation system such as the maximum power following control, etc..5. The trial production and experiments of whole system combining the solar battery with the small-sized light-weight power conditioner remain as future problems because we have spent a lot of time on research on improvement of the output current waveform of the resonant-type converter.This research is considered important because it has given a guideline to reduction of size and weight of the isolation-type power conditioner used in the photovoltaic generation system and has opened a way to realization of the easily available photovoltaic generation systems in a sense of awning.

我们对一种可以与太阳能电池板相结合的小体积、轻重量的电源调制器进行了基础研究，旨在开发和推广易于获得、安全、小体积、轻重量、价格低廉、可在遮阳篷意义上安装的光伏发电系统。利用功率mosfet对功率调节器的核心——谐振型变换器的基本电路进行了原型设计。找出了在脉冲宽度控制和频率控制相结合的变换器输出电压控制下实现软开关（零电压开关）工作的条件。仿真结果表明，如果变换器不具备双向功率转换的能力，在输出交流滤波器较小的情况下，变换器的输出电流波形会产生较大的畸变。给出了考虑几十kHz ~几MHz损耗的变压器和线圈的设计方法及损耗的减小方法。给出了一种统一谐振线圈和变压器的准则。为了考察光伏发电系统在特定条件下的运行特性，设计了仿真电路对其特性进行仿真。因此，将其与太阳能模型相结合，模拟太阳能功率的变化，将有可能评估光伏发电系统的性能，如最大功率跟随控制等。由于我们在改进谐振型变换器输出电流波形的研究上花费了大量的时间，因此将太阳能电池与小型轻质功率调节器相结合的整个系统的试制和实验仍然是未来的问题。本研究为光伏发电系统中使用的隔离型功率调制器的体积和重量的减小提供了指导，为实现遮阳篷意义上的光伏发电系统的易得化开辟了道路，具有重要意义。少
