This paper presents examples of a multi-instrument approach in ionospheric disturbance detection over the Eastern Mediterranean region. The results presented are based on a scientific initiative to establish an ionospheric monitoring network over Cyprus and Egypt by linking the corresponding instruments in operation in the two countries: a group of three Coherent Ionospheric Doppler Receiver (CIDR)...
This paper presents an analysis and design procedure of a three-phase three-level nine switches voltage source inverter using the space vector pulse width modulation (SVPWM) control scheme. The proposed inverter consists from 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. Where ideal switches and diodes...
