How pulse width modulation PWM in IGBT based rectifier for VFD / VVVF, STATCOM works, is explained in the video tutorial. PWM (pulse width modulation) technology is used for IGBT based rectifier in VFD/VVVF for train engine, an electric locomotive and also in STATCOM for reactive power control. The Full form of VFD is the variable frequency drive. The full form of VVVF is the variable voltage variable frequency drive. IGBT and pulse with modulation (PWM) based rectifier for variable frequency drive is designed using IGBT and diode both in the rectifier along with one inductor at the input supply. IGBT is switched ON and OFF at high frequency using the PWM concept to control the input current, voltage across inductor and output DC voltage. It provides many advantages like unity power factor, very low harmonics, variable and controlled DC voltage, suitable for large voltage variation and frequency at the input, and power regeneration during application of the brake. Use of IGBT in the rectifier bridge, Operation of IGB and diode to control input current and charging of the capacitor is explained. Educational video tutorial on electricity, power electronics and electrical engineering 292 by G K Agrawal (Gopal Krishna Agrawal).
Further, the concept and working principle of the pulse width modulator PWM to control current explained in this video is also useful for STATCOM, reactive power control, SVC for load balancing and power factor control also.
The lecture is given by a person with industrial experience.

About the Site 🌐
This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.
As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
