This paper develops a robust tool for the treatment of AC side stability problems occurring in interconnecting PWM voltage source converter with passive LCL filter. An LCL filter can reduce the harmonics introduced by PWM switching frequency and guarantee low currents THD using small component values comparing to the L filter solution. Nevertheless, the(More)
A robust tool compensating stability problems occurring in interconnected voltage-source rectifier loads with input passive LCL filter is developed. An LCL filter can reduce the harmonics introduced by PWM switching frequency and guarantee low currents THD using small component values comparing to the well-known L filter solution. Nevertheless, the(More)
Parallel voltage-source inverters with common dc bus present very interesting advantages from an industrial point of view. Indeed, by paralleling several units the power supply system includes capability to handle high power requirement, modularity and the possibility of maintenance through redundancy, within an uninterruptible supply operation. However, a(More)
In this paper, we present a new current sharing technique on a general case of N paralleled DC-DC boost converters. The proposed optimization is based on the knowledge of individual boosts parameters. Every losses through the structure are modelled by equivalent resistors. Using an accurate online estimation of those resistors, we can determine the losses(More)
