This paper proposes a power electronic converter, with sinusoidal currents in high frequency transformer. High frequency power transformers are capable of replacing the bulky power transformers in power systems. The switching frequency of power electronic transformer, proposed in this paper, is independent of the value of leakage inductance. This is achieved with the help of a low pass filter, formed...
The use of component connection models (CCMs) is an approach to simulate large interconnected systems in an effective way. An interesting feature of this approach is that, for a circuit description, the specification of component characteristics and the specification of their interconnections can be separated. This feature can be used to create efficient simulation methodologies since the resulting...
Photovoltaic (PV) system is composed of several elements as solar cells, boost converter, inverter and load. Owing to the existence of converters, photovoltaic system is a hybrid system contains continuous dynamic and discrete dynamic. Traditionally, the power electronic converter is difficult to model. This paper illustrates the modeling method of hybrid system, especially finite automata model....
In this paper a small signal model of a power electronic converter is derived in the time domain. The paper first describes a large signal power electronic converter model with ideal switches. This model is then linearized to form a small signal model. An example of a buck-boost converter is used to show the highly linearized behavior of power electronic converters. Finally a discussion is presented...
