In this work discrete time current regulation methods for three-phase parallel active filters (PAF) are investigated. With emphasis on PAF applications, linear and hysteresis current regulation methods are studied and improvements on the discrete time implementation of the latter type without any additional analog hardware are provided. The dependency of the switching ripple filter (SRF) type on the PAF current regulator (CR) type is considered and design methods provided. A PAF is designed for a three-phase 10 kW diode rectifier load and studies are investigated through this system. The CR and PAF performances are studied by means of theory, simulations, and laboratory experiments. A DSP controlled PAF system is built and all the algorithms are experimentally verified. The study shows that the resonant filter linear current regulator and the improved discrete time hysteresis current regulator with appropriate SRF types perform satisfactorily.

Performance enhancement and comparison of discrete time current regulators for parallel active filters
Ozkaya, Hasan; Senturk, Osman Selcuk; Hava, Ahmet Masum (2007-09-05)
Discrete time linear and hysteresis current regulators (CR) for three-phase parallel active filters (PAF) are reviewed and evaluated. A novel discrete time hysteresis current regulation method with current oversampling and flexible PWM release capability, DHCR3, which has superior overall performance and simple implementation (no additional hardware) is proposed. Switching ripple filters (SRF) suitable for each CR type are designed. A DSP controlled PAF is designed and built for a three-phase 10 kW diode re...
Performance analysis and comparison of reduced common mode voltage PWM and standard PWM techniques for three-phase voltage source inverters
Un, E; Hava, Ahmet Masum (2006-03-23)
This paper investigates the performance characteristics of the reduced common mode voltage (RCMV) PWM methods for three phase voltage source inverters and provides a comparison with the standard PWM methods. PWM methods are reviewed and their pulse patterns and common mode voltage patterns illustrated. The AC output current ripple, DC link input current ripple, and output voltage linearity characteristics of each modulation method are thoroughly investigated by analytical methods and simulations. The analys...
Investigation on Series Active Filter Compensated High Power Grid-Connected Voltage Source Inverters with LCL Filter
Usluer, S. Nadir; Hava, Ahmet Masum (2014-09-18)
This paper deals with Series Active Filter (SAF) based damping methods for the LCL filters of three-phase, grid connected, low voltage, high power Voltage Source Inverters (VSIs). The inherent resonance problem of LCL filters is damped via passive or active damping methods. Passive damping methods employing damping resistors create significant power losses reducing the overall system's efficiency for high power inverters. Active damping methods, on the other hand, are not applicable due to inverter's limite...
Performance Analysis, Filter Component Sizing, and Controller Structure Selection of Small Capacitor Diode Rectifier Front End Inverter Drives
Aban, V. Volkan; Hava, Ahmet Masum (2014-09-24)
In this study, the input filter design and dc-bus voltage control of ac motor drives utilizing low capacitance film capacitor are investigated. The dc-bus voltage instability problem arising due to the resonance between the dc-bus capacitor and circuit inductances is explained. A dimensioning algorithm of dc-bus filter components for stable operation is given. The simulation results of the low capacitance motor drives with and without dc-link inductor are provided to observe the stability of the dc-bus at d...
Performance Analysis of Reduced Common-Mode Voltage PWM Methods and Comparison With Standard PWM Methods for Three-Phase Voltage-Source Inverters
Hava, Ahmet Masum (2009-01-01)
This paper surveys the reduced common-mode voltage pulsewidth modulation (RCMV-PWM) methods for three-phase voltage-source inverters, investigates their performance characteristics, and provides a comparison with the standard PWM methods. PWM methods are reviewed, and their pulse patterns and common-mode voltage (CMV) patterns are illustrated. The inverter input and output current ripple characteristics and output voltage linearity characteristics of each PWM method are thoroughly investigated by analytical...
