Performance Analysis of T-type Inverter Based on Improved Hysteresis Current Controller
(Balkan Journal of Electrical and Computer Engineering, 2019)
This paper presents an improved hysteresis current control method for five level T-type inverter. The proposed method is based on four hysteresis levels and performed to generate switching signals of fundamental transistors ...
Impulsive Noise Models Used in Power Line Communications
(Balkan Journal of Electrical and Computer Engineering, 2019)
In a communication system, noise has always been
considered as a serious cause of error. Although most common
noises can be modeled by well-known Gaussian distributions,
some communication systems experience other types ...
