“…This structure supplied several machines simultaneously (SMM) and non-sequential manner [2]. The originality of the present paper is the use of an optimisation approach to compare two converter's topologies in order to select the most suitable architecture allowing to respect specifications [3][4][5][6][7][8] and reaches an actual objective that is to provide virtual prototyping tools especially for power converters [9][10][11][12] to avoid physical prototypes as much as possible.…”

This study deals with pre-sizing methodology of embedded static converters using optimisation for which high performances of weight, volume and efficiency are required. Moreover, in the automotive and aircraft domains, power-sharing architectures should be an other investigation path to reach such performances. The idea of power sharing is suitable and judicious if the actuators are in the same power range. In this study, the authors consider three electrical machines sequentially driven. The first solution is to use three independent inverters without power sharing, the second one is an inverter with a power-sharing system. A non-conventional DC-AC matrix converter is proposed to replace classical inverters. So as to overcome a priori power designers habits, a general modelling and optimisation is performed to provide a virtual prototyping tool to avoid physical prototyping because of their exhaustive cost. The objective function is the overall volume (mainly the heatsink's volume). The optimisation results are presented and discussed. These preliminary results, under a three-AC drive assumption, show clearly that {inverter + power sharing system} and even the DC-AC matrix converter have an overall volume lower than the three-inverter solution.

“…The originality of the present contribution is based on three aspects. The first one is about the generalised power switch modelling approach [2][3][4][5]. It is applied to a unidirectional voltage and bidirectional switch for voltage inverter.…”

The increasing need for higher efficiency, weight and volume reduction in embedded applications is a starting point of this study which focuses on a pre-sizing methodology of power converters based on virtual prototyping tools to avoid physical prototypes. From a general point of view, the mutualisation of a three-phase inverter with the help of a power sharing system is introduced. The proposed design approach optimises N inverters and a {one inverter + N-power sharing system} topologies based on a generalised modelling and a virtual prototyping tool. The presented results based on a 3 kW-270 V DC bus application show that in addition to the switching frequency and the ambient temperature, the number of sequential loads is also a key of the optimisation parameters. Therefore the proposed methodology based on an optimisation process allows the power designers to compare N inverters and {one inverter + N-power sharing system} as a function of the load number N.
