Abstract The current work addresses the results of the studies on hybrid radio frequency (RF) / free-space optical (FSO) system. We found that the RF link is impacted by Rayleigh fading and the Gamma distribution designed the optical signal fluctuations. Further we derived the hybrid RF/FSO system using the outage probability expression. We have further observed the effect of the atmospheric... Read More

Abstract In this paper, we proposed the optimal trajectory control system (CS) of series resonant converter (SRC) operating at constant frequency. The state-plane analysis of SRC designed the control system which is based on the principle of the Analog Behavioral Modeling. This helps in deciding the time intervals in the commutation process when the oscillating circuit voltage and current alter according... Read More
