Abstract :
In case of electro-technical body tests, it is necessary to use voltage-controlled converters with large bandwidth and fast dynamics. Recently, a novel pulse width modulation has been investigated. It has permitted to design regulators in order to reach an accurate tracking of current or voltage references. Here, the first version of the voltage controller is improved in order to target these new specifications. Indeed, it is necessary to get a bandwidth of a couple of kiloHertz, with a phase shift lower than ten degrees. This goal is reached
