Robust laser frequency stabilization by serrodyne modulation.
We report the relative frequency stabilization of a distributed feedback erbium-doped fiber laser on an optical cavity by serrodyne frequency shifting. A correction bandwidth of 2.3 MHz and a dynamic range of 220 MHz are achieved, which leads to a strong robustness against large disturbances up to high frequencies. We demonstrate that serrodyne frequency shifting reaches a higher correction ban...
متن کاملA New Control Method for Single-Phase Grid-Connected Inverter Using Instantaneous Power Theory
Because of installation for local consumers and since it is free of all contaminations, connecting photovoltaic cells to the grid via single-phase inverter is significantly on the rise. In this paper, a new simple current control is proposed for a single-phase grid-connected voltage source inverter. Using the PQ theory and modelling a single-phase system as an unbalanced three-phase system, a m...
متن کاملA pulse-frequency modulation sensor using memristive-based inhibitory interconnections.
This paper proposes a programmable inhibitory interconnection network between pixels in an array of novel low-voltage Schmitt-trigger-based PFM sensors that will be of interest for future applications in memristor-based early vision processing. In addition, a new low-power inverter-based pulse-frequency modulation (PFM) design and its integration with the network is also presented. To ensure no...
متن کاملLow-Frequency Pulse Width Modulation Control Methods of Ultrasonic Motor
Because of the serious non-linearity and coupling among state variables caused by the complex energy conversion process in ultrasonic motor, the motion control strategy of ultrasonic motor still need to be studied in detail to obtain better performance. As a kind of special control method, the low-frequency PWM control strategy can make the on-line optimum control easier, and may be an effectiv...
متن کاملA New Pulse Duty Cycle Control Method with Pulse Frequency Modulation for Light Load Applications
LEDs are likely to be used for general lighting applications due to their high efficiency and longer life. To cover wide output range on lighting application some of control methods are adopts. In the proposed method, the interleaved DCM fly back converter is favoured. DCM operation can accomplish high PF for wide output power range. To achieve high efficiency, new pulse duty cycle control meth...
