摘　　要：针对根据负载功率调速的柴油发电机组,提出了整流-升压-逆变-滤波的电能变换结构,并采用CPLD对关键信号进行检测与控制。通过对该电能变换装置的功能需求的分析,确定了系统的结构形式。分析了以TMS320F2808为核心的控制电路、主功率电路、驱动电路、采样电路的工作原理,提出了扰动补偿+闭环的复合控制策略。通过整机实验,对系统的性能进行了测试。实验结果表明,变换器可适应负载的变化,输出电压幅值、频率均稳定的电能。The converting structure of rectify-boost-invert-smoothing was introduced for the diesel generator set,whose speed was controlled based on various loading power. CPLD was used to inspect and control the key signal. After analyzing the functional requirements of the power conversion device, the system scheme was proposed. The strategy of disturbance compensation and closed-loop combined control was designed. The principle of TMS320F2808 control circuit,main power circuit, drive circuit and sampling circuit were introduced in detail. The system preference was measured by thewhole experiment. The experiment results show the output-voltage of the converter has constant amplitude and frequency,which can adapt to the change of the load.
