This paper studies the space vector pulse width modulation technique (SVPWM) for the three-phase three- level nine switches voltage source inverter. The proposed inverter is based on the two level inverter topology where it consists of a main inverter switches Q1, Q2, Q3, Q4, Q5, and Q6, an auxiliary three bidirectional switches S1, S2, and S3 and two capacitor banks C1, and C2. Ideal switches and...
Power system signals are often contaminated with harmonics and noise. It is preferable to determine these harmonics for analysis, control and design of power system devices and protection. This paper presents an efficient technique for harmonics current estimation based on adaptive notch filter (ANF). The proposed filter structure is tested, simulated and implemented in a digital signal processor...
