| Abstract |
A new way for designing and analyzing the Active Filters based on voltage source converters is
presented. A systematic step by step design procedure is explained covering almost entire electrical
system design of Active Filter. This method not only enables a completely new design of a system but
can also be used to analyze an existing system to find its suitability for a given load. As the proposed
technique is based on time domain it can be implemented online in the control processor to analyze &
monitor various. For example the junction temperature of the devices can be calculated online to
decide the current limits of converter thereby making it possible to operate the converter at its
maximum capability at all times. Even though voltage source converters are considered in this paper,
it can be equally applied to current source inverter based systems. MATLAB was used for developing
the design program. This offline program executes in less than a second on a Pentium Computer. The
program takes basic parameters like load current waveform, supply voltage waveform, percentage
ripple current & voltage etc as inputs and produces the specifications of various components as output.
An online implementation has been done on the Active Filter Controller and the additional
computational time required was only a small fraction of the control code of the Active Filter. Being
generalized in nature the approach can be used for designing other systems like UPS. |
