Adaptive Hysteresis Current Control Of A Pwm Inverter At Constant Modulation Frequency Applied To Shunt Active Power Filters by Rondineli Rodrigues Pereira, Carlos Henrique da Silva, Luiz Eduardo Borges da Silva, Germano Lambert-Torres, Bimal K. Bose

“… This paper proposes a novel adaptive hysteresis current control strategy of a voltage-fed PWM inverter, where the switching frequency always remains constant and the harmonic ripple is minimum, irrespective of dc link voltage fluctuation and load parameter variation. The developed algorithm works well for single-phase as well as multi-phase inverters, although single-phase inverter operation, particularly in active harmonic filter mode, is emphasized in this paper. …”

Experimental study and techno-economic evaluation of an active fault detection kit in the prospect of future zero energy building installations by Christos Pechlivanis, Nick Rigogiannis, Andreas Tichalas, Faidra Kotarela, Nick Papanikolaou

“…This simple, flexible, self-powered and compact kit is capable of detecting faults, such as power theft (meter tampering), unintentional islanding and neutral conductor loss. Its operation is based on harmonic voltage injection, in series with the electrical installation, through a low-power H-bridge inverter and a current transformer, along with the corresponding harmonic current measurement, to estimate the impedance and effectively detect faulty conditions; the fast and robust Goertzel algorithm is utilized. …”
