A CCV is a frequency changer which can be direct or through a dc link. He worked as CCV expert in a litigation case in Australia and also wrote technical papers on the subject.
In this converter, AC is first converted to DC, filtered and then converted to fixed or variable frequency AC. The former is for UPS system and the latter is for AC motor drive.
DC-DC converter is usually for regulated power supply to electronic apparatus. It can also be transportation in a DC motor drive.
This is usually for AC motor drive or UPS system.
He has written 4 books on electric motor control. Motors can be DC or AC.
A power converter using power semiconductor devices is usually defined as power conditioner.
A power converter that generates DC from AC.
A thyristor that can be turned on and off by gate pulse.
Electric power conservation is very effective using power electronics.
Control of converters are possible by ASICs and DSPs.
Power conversion and control by power sem. devices.
Power supply can be DC or AC and this uses power electronics heavily.
PWM controls voltage of inverter with minimal harmonics.
Wind, PV or fuel cells are possible renewable energy systems which are very important energy sources in recent years.
UPS system gives reliable DC or AC supply when the utility power fails.
