Modeling and Control of Modern Electrical Energy Systems

2Standard Power Electronic Converters

This chapter is devoted to the understanding of standard power electronic converters. Topologies such as standard buck, boost, buck-boost, and the voltage source converter (VSC) are reviewed. The VSC study is divided into single-phase and three-phase VSCs. The single-phase VSC is also divided into half-bridge and full-bridge topologies. For each converter, the topology is introduced, the pulse-width modulation (PWM) technique to generate the gating signals is discussed, and finally an average control model is derived. This chapter lays the foundation for modeling of distributed energy resource (DER) systems for the purpose of analysis and control design.

2.1 Standard Buck Converter

The standard buck converter is shown in Figure 2.1 which comprises a unidirectional switch and a diode . It is the interface between side A and side B and the power flow direction is obviously from side A to side B, i.e. the input side to the output side, respectively. The inductance value is , and denotes the totality of cable's resistance, the inductor's parasitic ...
