摘要

本文的目标是研究和实现一个光伏转换链，该转换链主要由太阳能电池板、由微控制器和负载产生的信号脉宽调制(PWM)控制的功率转换器组成。为了开发这项工作，我们携带了一个斩波降压，我们实现了斩波降压和不同的相关卡:基于PIC 18F4550的测量、保护和控制卡。这一个产生一个PWM控制信号到10千赫频率，与可变占空比。对系统进行了实际验证，实验结果表明系统功能良好，产率令人满意。

Realization of a photovoltaic chain with a chopper controlled by a microcontroller PIC 18F4550

The objective of this work is the study and the realization of a photovoltaic conversion chain which consists mainly of a solar panel, a power converter controlled by a signal pulse width modulation (PWM), generated by a microcontroller and an electric load. For develop this work, we carried a chopper Buck we achieve a chopper Buck and different associated cards: cards of measurement, protection and control based on the PIC 18F4550. This one generates a PWM control signal to 10 KHz frequency, with variable duty cycle. A system practical validation is performed, which experimental results showed a good functioning of the achieved system with a satisfactory yield.
