High-power converters based on elementary switching cells are more and more used in the industry of power electronics owing to various advantages such as lower voltage stress and reduced power loss. However, the complexity of controlling such converters is a major challenge that the power manufacturing industry has to face with. The synthesis of industrial(More)

We consider here systems with piecewise linear dynamics that are periodically sampled with a given period τ. At each sampling time, the mode of the system, i.e., the parameters of the linear dynamics, can be switched, according to a switching rule. Such systems can be modelled as a special form of hybrid automata, called " switched systems " , that are(More)
Today, electromagnetic compatibility seems to be one of the major constraints of power electronics converters and especially for variable speed drives. Unfortunately, it is too often regarded as the last phase of the development of a converter since it represents the last step of its marketing. The estimation of conducted and radiated disturbances by(More)
An analytical model of both EMC and losses of a PWM inverter is presented, taking into account the most significant parameters. EMC representation replaces semiconductors with equivalent disturbance sources. Then, solving is achieved using simple transfer functions. Conduction losses are evaluated from on state voltage drop (taken from datasheet) and(More)

This paper proposes a method to synthesize a full wave control applied to a multilevel modular converter (MMC). This method guarantees the output waveform and the balancing of the capacitors. Numerical simulations and experiments are used to check the validity of the approach.
The design of static power converters makes intervene an important number of variables as well as several different kinds of constraints. The goal of this work consists in introducing the EMI constraint at the time of the power electronic circuit's design while leading an accurate analysis of the conducted sources of perturbations. The developed models aim(More)
