    • The present invention relates to a quasi-resonant controlling and driving circuit and method for a flyback converter. In one embodiment, a controlling and driving circuit for a flyback converter, can include: a differentiation circuit configured to receive a third controlling signal and a drain-source voltage of a main power switch of the flyback converter; where the drain-source voltage is configured to be differentiated by the differentiation circuit to generate a differential voltage when the third controlling signal is active within an interval that the main power switch is shut-off; a valley voltage detection circuit coupled to the differentiation circuit, and configured to receive the differential voltage; and where a valley controlling signal is configured to be generated by the valley voltage detection circuit to achieve quasi-resonant driving for the main power switch of the flyback converter when the differential voltage crosses zero with a positive slope.
    • 本发明涉及一种用于反激式转换器的准谐振控制和驱动电路及方法。 在一个实施例中,用于反激式转换器的控制和驱动电路可以包括:微分电路,被配置为接收反激式转换器的主电源开关的第三控制信号和漏 - 源电压; 其中,所述漏极 - 源极电压被配置为由所述微分电路微分,以在所述第三控制信号在所述主电源开关被切断的间隔内有效时产生差分电压; 耦合到微分电路的谷值电压检测电路,并且被配置为接收差分电压; 并且其中谷值控制信号被配置为由谷值电压检测电路产生,以当差分电压以正斜率跨越零时,实现用于回扫转换器的主电源开关的准谐振驱动。

    • A Cooperative Grid Based Picture Archiving and Communication System (Grid PACS for short) is a multimedia (imaging) medical information archiving, communication and application system used in hospitals. Based on the existing PACS servers, workstations, or other networked multimedia image management systems, it adds and integrates grid-based network functionality into the existing image systems to form new grid-based image communication and management system.It uses service-oriented and event-driven concepts and methods to design and implement a new grid-based image communication and management system to solve the problems encountered in distributing archived image information, coordinating work and managing in a virtually centralized way (Virtual Super-PACS) of different PACS or archiving systems under varied operating environments.
