To suppress the influence of impulsive noise spikes (outliers) from the direction of arrival of the desired GPS signals, a combination of the Householder multistage Wiener filter (HMSWF) and the recently introduced Minimum Module Cascaded Canceller (MMCC) is employed to compose a hybrid structured HMSWF (HS-HMSWF) method. The enhanced algorithm is employed by space-time anti-jamming processing ...

This paper presents multicarrier PWM strategies for three phase cascaded seven level Z-source inverter. Multilevel inverters posses the advantage of reduced harmonics, high-power capability and high-voltage level. Impedance network in the cascaded multilevel inverter circuit will perform boost operation. This paper focuses on multicarrier sinusoidal pulse width modulation (MCSPWM) strategy for ...

To enable the integration of large-scale renewable energy, hybrid HVDC technology, which combines technical advantages LCC-HVDC and VSC-HVDC, is being gradually deployed in power grid nowadays. The operation Wu-dong-de Hybrid DC Project Jian-su cascaded MTDC has proved its advantages. However, for simultaneous application different converter station technologies system, control strategies becom...

This paper explains a control strategy SHE-PWM and a closed loop control of the cascaded multilevel inverter based on the modulation index. The modulation index is taken as the feedback to the cascaded multilevel inverter, the proposed system reduces the total harmonic distortion by optimizing the angles of the inverter and the DC voltage sources applied to the cascaded inverter. The specific l...
