Computer-Aided Design (CAD) is one of the many tools used by
engineers and
the type of software in question. There are several different
types of CAD. Eachof these different types of CAD systems require
the operator to think differently
about how he will use them and he must design their virtual
components in adifferent manner for each. Power electronics is one
of the many fileds that use computer software to
help engineers in analysis, simulation and design of their
components. This course will present the basics of CAD/CAE for
Power Electronics and the
course oal is to ensure the students with the followin knowled
e:
The main used software for CAD/CAE in power electronics; The
methods of modeling and simulating an electrical power converter;
The analysis and design of the power electronics circuits;
The basic rinci les behind the model of an electrical
circuit.

,number of phases. A controller accomplishes the power flow
controlbetween the two sides of the converter, in which the
conversion of voltagesand currents should be achieved with as high
energy-efficiency and highower densit as ossible.
Among multiple applications that use power electronics interface
for powerflow control, the most common and important applications
are:
Adjustable speed drives (stationary and mobile
applications);
Converters for interfacing renewable energy sources to the
grid.

The efficiency of power converters
The efficiency is the most important feature of a power
electronicsconverter.
Hi h efficienc lead to low ower losses within converter. Also,
small size
and reliable operation is then feasible. The efficiency is a
good measure of converter performance.
A goal of the current technology is to construct converters of
small size and.
