课程名称：学习功率电子及其应用 课程概述：功率电子是电气工程的一个分支，专注于高电压和电流的处理，以提供支持多种需求的电力。作为一个多学科领域，功率电子旨在处理、控制和转换电能。功率电子系统广泛应用于电力生成、电力传输、电力分配和电力控制等领域。在这些应用中，使用功率半导体器件对输入电压和电流进行切换，以提供所需的输出。为了适应高电压和高电流，基本半导体器件的构造如二极管、场效应管（FET）和双极结晶体管（BJT）都有所改进，因此产生了受控硅（SCR）、功率二极管、功率MOSFET、功率BJT、绝缘栅双极晶体管（IGBT）、门关断硅整流器（GTO）等。功率电子的基本功能包括（1）电力转换：交流转直流、直流转交流、交流转交流；（2）电力调节：消除失真、谐波、电压下跌和过电压；（3）对电流、电压阻抗和相位角等电气参数进行高速和/或频繁控制。在本课程中，您将学习功率电子及其应用，包括有关SCR（硅控制整流器）、功率MOSFET和IGBT（绝缘栅双极晶体管）的知识。课程内容还涵盖单相整流器（R和R-L负载）的电路图、波形和方程式，逆变器（详细类型），转换器（包括分类和数值分析），谐振转换器以及功率电子应用。在功率电子应用方面，您将学习不间断电源（UPS）及其类型、电子镇流器、LED灯、风扇调节器等。 期待您加入这门课程，深入了解功率电子的世界及其重要应用！
Power electronics is the branch of electrical engineering that deals with the processing of high voltages and currents to deliver power that supports a variety of needs. Power electronics is a multidisciplinary branch of electrical engineering. It focuses on processing, controlling, and converting electric power. Power electronic systems are used in a variety of applications, such as Power Generation, Power Transmission, Power Distribution and Power Control. In all these applications, the input voltages and currents are switched using power semiconductor devices to provide desired outputs. The construction of basic semiconductor devices such as diodes, FETs, and bipolar junction transistors (BJTs) are altered to withstand high voltages and currents. As a result, we have silicon-controlled thyristors (SCRs), power diodes, power metal oxide semiconductor field effect transistors (MOSFETs), power BJTs, insulated gate bipolar transistors (IGBTs), gate turn-off thyristors (GTOs), and so on.The basic functions of importance for power electronics are (1) power conversion, ac to dc, dc to ac, ac to ac, (2) power conditioning to remove distortion, harmonics, voltage dips and overvoltages, (3) high speed and/or frequent control of electrical parameters such as currents, voltage impedance, and phase angleHere you are going to learn about power electronics and its applications. Contents which you are going to learn all about SCR (Silicon Controlled Rectifier) , Power MOSFET and IGBT (Insulated Gate Bipolar Transistor). Single Phase Rectifier R and R-L Load (Circuit Diagram, Waveform and Equations), Inverters (Types in Details), Chopper (about Chopper, classifications of chopper and numerical), Resonant converters and Power Electronics Applications.In power Electronics applications you will learn UPS (uninterruptible power supply ) and its types, Electronic Ballast, LED Lamp, Fan Regulator etc.
