Power Electronic Converters

5Dynamic Modeling of Current-Output Converters

5.1 Introduction

The use of energy storage either to ensure uninterrupted operation (cf. Figure 5.1) [1] as a primary energy source [2] or assisting the operation of the system [3–6] is growing rapidly due to the increasing use of different battery-powered devices as well as due to increased utilization of renewable energy sources incorporating intermittent nature in energy production. In such applications, the power electronic converters have to be able to operate in two different operational modes, as shown in Figure 5.1b: When the storage battery is fully charged, the power electronic converter will maintain the charge operating at constant voltage-output mode (cf. Figures 5.1b and 5.2a). ...
