“…The solution for the described problem is to eliminate eigenvalues equal to zero while calculating spectral components X i and to reduce the order of the system. In the case of r zero eigenvalues, the number of nonzero eigenvalues is m + n − r , and the originally system (20) becomes…”

In this paper, a time-domain simulation of the DC-DC converters' dynamic behavior is described. Corresponding to the state-space model for each possible operation mode of the circuit, an analytic solution is provided. Converter's regulator is discretized using the pole-zero placement technique based on its Laplace transfer function. An algorithm results in a very accurate simulation due to the exact solution of the circuit's equations.

“…Both simulations of theĆuk converter whose results are shown in Figs. 6 and 7 are verified using PLECS [20] and GeckoCIRCUITS [21]. Originally simulations were done with 100 points per period, but the number of points can be decreased to 30 points per period with the same simulation results.…”

Abstract-We present the analysis, design, and experimental implementation of a fault diagnosis method for switching power converters using a model-based estimator approach. The fault diagnosis method enables efficient detection and identification of component and sensor faults, and is implemented on the same computation platform as the control system. The modelbased estimator operates in parallel with the switching power converter, and generates an error residual vector that can be used to detect and identify particular component or sensor faults. This paper presents an experimental demonstration for a 1.2 kW rack-level uninterruptable power supply (UPS) dc-dc converter for data center applications. Simulation and experimental results demonstrate fault detection and identification for various component and sensor faults in the converter. Moreover, we show that the proposed fault diagnosis design and analysis methods are applicable to a broad class of converter topologies and fault types.

“…In these applications the inverter is normally a small part of a large system and the dynamics of the inverter have a small impact on the overall system. Inverters are sometimes modelled in a space-state formulation with the power devices in the inverter represented as ideal switches [5]. Under this assumption some accuracy is lost but the simulation time is normally improved by reducing both the time required by an analyst to set up a simulation and the time taken by a computer to produce the result.…”

The growth of distributed generation has led to distribution systems with a mixture of rotating machine generators and inverter interfaced generators. The stability of such networks needs to be studied through analysis of state-space models and so suitable models of inverters are needed to complement the well established models of rotating machines. Just as machine models include features such as automatic voltage regulators and wash-out functions so too should the inverter model include phase-locking functions and internal control loops.This paper develops the model for voltage source inverters with an internal current control loop, an outer power regulation loop, a measurement of average power and a phase-locked loop. The model is presented in detail and is formed with a state-vector similar to that used for rotating machines. The model includes non-linear terms but can be linearised about an operating point. The state-space model is verified against a component-level time-step simulation in Simulink/PLECS.
