Rectifiers and Inverters
In this video, you will learn about the critical roles of inverters and rectifiers in electrical systems, including their applications in various power conversion processes. Starting with an introduction to AC and DC power sources, the video delves into how these devices facilitate the conversion between alternating current (AC) and direct current (DC), a fundamental concept for powering electronics and achieving efficient energy transmission. You'll gain insights into the construction and operation of rectifiers and inverters, including the use of diodes and transistors like IGBTs or MOSFETs, to manage current flow and mimic AC waveforms through techniques such as pulse width modulation (PWM). Additionally, the video explores practical applications of these technologies in devices like variable frequency drives (VFDs) and uninterruptible power supplies (UPSs), highlighting their significance in industrial automation, renewable energy systems, and electric vehicles.
