For decrease the rectifier number
At first, there was cycloconverter with thyristors, then matrix converter with IGBT...
u refer cycloconverter and matrix converter
A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
Converter is AC to DC. Inverter is DC to AC
Step Down cycloconverters generally Lower the input frequency to a desired value.This has many applications such as activities requiring low frequency namely electric traction systems where simple DC commutating machines are provided with frequencies of order of 16 hz.
1. Induction Heating 2. Speed control of high power ac drives 3.Static VAR compensation 4.For converting variable spee alternator voltage to constant frequency output voltage for use as power supply in aircrafts.
I am working
When ur hot and ur working then it is hot working, if ur cold and ur working then it is cold working
No. She is working. She has been working.
I personaly use "working at" in terms of a company name, for example I am working at Tesco's or I am working at Sky the phrase "working in" is used in the terms of what sort of job is, for example I am working in a supermarket or I am working in the media industry. Hope this helps
