A phase-control power controller that converts a line voltage to an RMS load voltage includes a phase-control circuit connected to the line and load terminals and having an RC network that clips the load voltage. A load sensing circuit is connected across the load terminals that senses the ...
A phase-control power controller converts a line voltage to an RMS load voltage and includes a phase-control clipping circuit that clips a load voltage to provide the RMS load voltage. The power contr
it was assumed that a 300 kV AC, twin Grackle conductor line would be converted to bipolar ±300 kV DC to comply with corona and field effect limits. The converted line (shown in Fig. 2 employs the centre phase as a metallic return when one pole is out of operation. ...

has jitter in the time domain, corresponding to phase noise in the frequency domain). The spectrum shows the noise power in a 1-Hz bandwidth as a function of frequency. Phase noise is defined as the ratio of the noise in a 1-Hz bandwidth at a specified frequency offset, f m, to the...
MT-008 TUTORIAL Converting Oscillator Phase Noise to Time Jitter by Walt Kester INTRODUCTION A low aperture jitter specification of an ADC is critical to achieving high levels of signal-to- noise ratios (SNR). (See References 1, 2, and 3). ADCs are available with aperture jitter ...
was achieved without the introduction or overexpression of any catalytic enzymes inSynechococcus. Moreover, the glucose synthesis of recombinant PCC 7942 continued during the rapid growth phase independent of any environmental stress inductions (e.g., salts stress or dark treatment)23,24. In addition...
