International Journal of Smart Grid and Clean Energy Research on Active Power Filter Based on One-Cycle Control

One-cycle control (OCC) is a kind of nonlinear control technology. It is the most advanced reactive power compensation and harmonic suppression method. In the paper, a three-phase four-wire active power filter (APF) with one-cycle control is presented. This method does not need any measured quantities of three-phase input voltages and three-phase load currents, and also not need multipliers. Th...

Performance Scrutiny of Two Control Schemes Based on DSM and HB in Active Power Filter

This paper presents a comparative analysis between two current control strategies, constant source power and generalized Fryze current, used in Active Power Filter (APF) applications having three different modulation methods. The Hysteresis Band (HB) and first-order Delta-Sigma Modulation (DSM) as well as the second-order DSM is applied. The power section of the active power filter is viewed as...

Active Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

A Single-Phase Shunt Active Power Filter Based on Cycle Discrete Control for DC Bus Voltage

-A new control method for single-phase shunt active power filter (APF) is proposed. It integrates the DC bus voltage control and active power filter command current generation, according to the periodicity of source current and energy balance concept. The instantaneous harmonic compensation and linear DC bus voltage control are achieved, without complicated and involved control logic, by using ...
