The paper deals with the automatic generation of global model of static converters without the description of their environment. The considered models are average and exact models (i.e. with ideal switches). These models are obtained by using a software tool named AMG (for Average Model Generator) with a priori on the control mode and behaviour of the static converter. In this paper, an extension...
Recent innovation in vehicle systems has brought the extensive application of power electronics (PE) technology, which in turn has made the system more complex. The vehicle system is a multi-domain system, so that computer simulation has become an indispensable tool for vehicle system analysis. We propose a simulation method for the complex vehicle system based on the VHDL-AMS language. A multi-level...
A free SPICE version allowing general circuit simulation is used teaching power electronics. There is no lock on the circuit size, stabile and user friendly operation is experienced. A collection of transformer, converter and drive system models are implemented to investigate the usability of the programme in high power electronics.
The paper derives an analytical state-space average-value model of the direct symmetric topology of an 18-pulse AC-DC rectifier. The dynamic characteristics of the rectifier are fully represented while the model is time invariant and computationally efficient. The developed model, validated with comparison of the resultant transient and steady state behaviors with those obtained from detailed simulations...
In this paper a DC power plant for base transceiver station power supply is investigated. The supply system employs clean alternative energy sources, namely photovoltaic (PV) modules, wind turbines, a fuel cell as backup generator and a storage battery bank. A detailed description is made and experimental data are shown of a prototype system where the PV modules are directly connected to the DC bus...
This paper presents detailed models and simulators for an electrical on-board marine network. A one machine network is considered, and loads are described, initially, as equivalent RL circuits based on active and reactive powers, which results in a 5th order dynamic system. Then a more refined model with capacitances is proposed, which results in a 9th order dynamic system. This model represents the...
The Modular Multilevel Converter (M2C) is an emerging and highly attractive multilevel converter topology for medium and high voltage applications. In this paper, a new pulse width modulation (PWM) scheme will be derived. For this pulse width modulation scheme, characteristic simulated waveforms are described and analyzed.
This paper presents a comprehensive assessment of small-signal stability for a ldquomore-electricrdquo aircraft power system consisting of a synchronous variable-frequency generator which supplies several power electronic controlled loads via an 18-pulse autotransformer rectifier unit (ATRU) for AC-DC conversion. Functional models for key power system components and loads are derived. Numerical tools...
