On strongly dependent zero-inflated INAR(1) processes

Beran, Jan; Droullier, Frieder - In: Statistical Papers 65 (2023) 4, pp. 2527-2553

We consider INAR(1) processes modulated by an unobserved strongly dependent 0-1process. The observed process exhibits zero inflation and long memory. A simple method is proposed for estimating the INAR-parameters without modelling the unobserved modulating process. Asymptotic results for the...

A Varied VSVM Strategy for Balancing the Neutral-Point Voltage of DC-Link Capacitors in Three-Level NPC Converters

Gui, Shi Weng; Lin, Zhen Jun; Huang, Sheng Hua - In: Energies 8 (2015) 3, pp. 2032-2047

space vector modulation (VSVM) could guarantee the balance control of the neutral-point voltage. However, there still exist … some uncontrollable space vector regions. Based on VSVM, this paper proposes a varied virtual space vector modulation … (VVSVM) method for three-level NPC converters. Under complete modulation conditions, this method can control the balance of …

Analysis of Peak-to-Peak Current Ripple Amplitude in Seven-Phase PWM Voltage Source Inverters

Grandi, Gabriele; Loncarski, Jelena - In: Energies 6 (2013) 9, pp. 4429-4447

Multiphase systems are nowadays considered for various industrial applications. Numerous pulse width modulation (PWM … impact of these modulation schemes on the output peak-to-peak current ripple amplitude has been reported. Determination of … determined as a function of the modulation index, and a simplified expression to get its maximum value is carried out. Although …

Bayesian analysis of redistribution policy with a fixed scale

Cirier, Guy - HAL - 2014

A government has to finance a risk for its population. It shares the charges among the population with a fixed scale based on economic criteria. Various organisms have to collect and to redistribute fairly the subsidies. Under these conditions, when the size of the organisms is varied, the...
