【摘要】 发电机仿真器是一种电子装置模型,该仿真器能够模拟发电机及其调速、励磁调节的主要运行特性,但是发电机仿真器输出的三相正弦电压信号电压较低、驱动能力较弱,因此有必要研制一种与其相适应的功率放大器。本文通过对各类功率放大器的特性进行了分析和比较,研制了一种适合发电机仿真器的开关功率放大器(D类功率放大器),并针对发电机仿真器没有转子的特点,对带有功率放大器的发电机仿真器的并网运行进行了研究。本文按照功能规划、电路模块设计及仿真、整机原理电路图设计、印制电路板的设计、样机的制作及调试几个步骤详细阐述了该功率放大器的研制过程。经过仿真实验和实际装置实验的结果对比,验证了本论文所述方案的正确性和可行性。更多还原

【Abstract】 Generator simulator is an electronic device which could simulate the main operating characteristics of generator. Three-phase sine voltage signal of the generator simulator is low and the driving ability is weak, so we should develop a power amplifier which should be adapted to the generator simulator. In this dissertation, all kinds of power amplifier are analyzed and compared, and we developed a switching power amplifier (kind of class D amplifier) which is suitable for the generator simulator. The generator simulator does not have the rotor, according to the characteristic of the generator simulator, we make some research on generator simulator with a power amplifier combined in the grid.In this paper we expound the exploring process of the power amplifier, such as the function planning, design and simulation of electric circuit module, design of PCB board, manufacture and debug of the model machine. By analyzing the experiment, the design results gained emulation experiment and the actual device scheme is proven to be valid and feasible.更多还原
