Abstract

Nowadays CAD tools are widely used in power electronics. Power circuit simulators as well as some other dedicated tools allow reducing developing times. In this paper a new and efficient CAD tool for power electronics compensator design is presented. This tool incorporates some new concepts and algorithms oriented to obtain the optimal loop performance through the compensator design. The CAD tool allows easy designing of PWM regulated converters since it provides an easy and friendly interface tool to design the compensator; both from the conventional topologies and the small signal AC analysis of power circuit simulators.

Abstract

In order to reduce developing times when designing a power converter, it is very useful to have an initial design criterion that lead to a stable feedback loop. In this paper a new concept for power electronics compensator design and optimization has been developed. This concept provides the different combinations of crossover frequency and phase margin which lead to stable solutions. Other optimization features are also provided, such as the relationship between the phase margin and the setting time when the crossover frequency is placed below the power stage resonant frequency.

Abstract

The design of linear compensators is usually based on the frequency response of the system, considering phase margin PM and cross-over frequency fc as the initial specifications. Applying the k-factor method for synthesis of linear compensators, not all combinations of fc and PM yield feasible or stable designs, and in many cases the design procedure is based on a trial and error procedure. The objective of this paper is to define the fc-PM design space of linear compensators designed applying the k-factor method. This design space can be used to determine in a straightforward way the most appropriate compensator for a given topology, sensor and modulator.

Abstract

The development of power converters leads to design the control loop. In order to reduce developing times, it is very useful to have an initial design criterion that lead to a stable feedback loop. In this paper a new concept for power electronics compensator design and optimization has been developed. This concept provides the different combinations of crossover frequency and phase margin which lead to stable solutions. On the other hand, in order to optimize the performance of the control loop, other optimization features are also provided, such as the relationship between the phase margin and the settling time when the crossover frequency is placed below the power stage resonant frequency.

Abstract

Nowadays, black-box behavioral models of power converters are becoming interesting for system-level analysis. These models can be used to evaluate the response of power electronics systems which are composed of commercial converters, since they can be fully parameterized by analyzing the actual converter response. First black-box models of power converters have been recently proposed, but all of them are oriented to DC-DC converters. However, three-phase voltage source inverters are usually applied in current power electronics-based systems, such as aircraft power systems, and a black-box modeling method of this kind of converters has not yet been proposed. In this paper a large-signal black-box modeling method of three-phase voltage source inverters is proposed. The identification of the model is based on the analysis of the converter transient response, which is obtained by means of a set of simple experiments and easily usable fitting algorithms. An experimental validation of the proposed method has been carried out on a 5 kW actual inverter applied on an aircraft power system test bench.

Abstract

Today, black-box behavioral models of power converters are becoming interesting for system-level analysis. These models can be used to evaluate the response of power electronics systems which are composed of commercial converters, since they can be fully parameterized by analyzing the actual converter response. In this paper a new identification method of black box models for DC-DC converters is presented. This method is based on the analysis of the step transient response of the converter, which is obtained by means of simple experiments. The identification of the model is carried out using well established fitting algorithms, which can be applied using commercial tools.
