Osaamistavoitteet
The course gives basic understanding on the method of dynamic modeling in the field of power electronics. After taking the course the student can define dynamic models for DC-DC converters and use them in efficient design of power electronic systems and, thus, avoiding trial-and-error type of design. The student becomes familiar with control design in the frequency-domain and is able to implement stable feedback control in simulator and predict the control performance based on stability margins. The student knows how to evaluate the effect of nonideal sources and loads, such as a photovoltaic generator and input/output filters on the dynamic performance of the DC-DC converter. The student understands the concept of impedance-based interactions and can take measures to minimize them in power electronic systems.
