Ir'I narrow pulse width detection circuit Figure 9 shows the waveform measured too broad and too narrow when the waveform has a rising edge pulse output, which can trigger the alarm, meet the design requirements. Figure 1O pulse width measurement circuit for the experimental determination of the waveform, can be seen from Figure 1O input signal from the rising edge of the counter starts counting when input signal is high, and only at the count, falling edge of the input signal and the counter stops counting holds the count unchanged until the arrival of the next rising edge of reset signal count. 3 Conclusion This article describes the Kicker power supply voltage monitoring system to achieve the overall structure and function to explain the thyristor conduction leakage error detection, pulse detection, pulse width measurement and pulse counting circuit design of each functional module theory, confirmed by simulation and experimental results the feasibility of the system design. The detection system has some versatility, and also separate out the various application modules, with relative independence. System described in this article have been applied to CSR Main Ring Kicker power system. In this work, the Korea Institute of High Energy Physics researcher Qian, Wei Xianzu researchers provided valuable advice and great help, since together with gratitude.

High Daqing (1969 a) male, Associate Professor, Ph.D., nuclear technology and applications expertise, with a special power supply is in accelerator research. IR's 100V MOSFET integrated solutions for the world leaders in power management technology, International Rectifier (InternationalRectifier,sac hermes birkin, referred to as IR) has introduced the IRF4000 type IOOV devices. The device will be four HEXFETMOSFET integrated in a power MLP package, to meet the Power over Ethernet (Power an 0ver-Ethernet,abercrombie france, referred to as PoE) applications. The new device is compliant with the network and communications infrastructure systems IEEE802.3af standards such as Ethernet switches, routers and hubs, to provide 15W of power per port, and can replace one of four independent SOT 223 package the MOSFET. The reduced footprint is equivalent to saving 80% of the space, or the equivalent of a typical 48-port circuit board in the three square inches of footprint.
