PPT-AC-AC Converters Module II

Lecture 9 Dr Oday A Ahmed ACAC Voltage Controller Converter Cycloconverter Indirect Matrix Converter direct Matrix Converter Or AC Choppers ACAC Voltage Controller Converter There are two different types of thyristor control used in practice to control the ac power . These operating ranges may be broad and in some cases may overlap It is usually not possible to derive any arbitrary output voltage from the entire range of permissible input voltages There are several factors that can cause this including the inter A new family of complementary MOS multiplying digitaltoanalog converters has arrived on the scene and promises to make microprocessor interfacing truly universal The doublebuffered MICRODAC units eliminate many common problems bridging the way to a Most Interpoint power converters have partial input line filters consisting of a single inductorcapacitor LC section which reduce the differential spectral noise components to about 30 mA pp This is adequate for many applications However where lower Converters.
