    • A power converter employing a magnetic device including a magnetic core and first and second tapped windings. Each winding of the magnetic device has first and second winding sections, respectively, coupled to the magnetic core, wherein the first and second winding sections are formed from a formed and folded planar conductive sheet. The magnetic core includes a common leg, a plurality of outer legs, and a top plate. The first and second winding sections are constructed with a formed and folded planar conductive sheet formed with structures usable as pins in a through-hole, surface-mount, or combined printed wiring board assembly process. The outer legs at either end of the magnetic core are positioned back from magnetic core ends, and the magnetic core is formed with a stepped structure to accommodate winding pins in a surface-mount printed wiring board assembly process.

    • The present invention provides a method of scheduling packet in a wireless telecommunication system, in which the user packet queues to be transmitted are divided into the user packet queues with lost packet and the user packet queues without lost packet; for the user packet queues with lost packet, if a real time lost ratio of packet for the user excesses a predetermined lost ratio threshold of packet, terminate a connection to the user; if the real time lost ratio of packet for the user does not excess the predetermined lost ratio threshold of packet, schedule the user packet queues according to a volume of the lost ratio of packet; for the user packet queues without lost packet, schedule according to packet lengths, channel quality states, time delays and time delay jitters. The present invention decreases the packet lost ratio by giving priority to scheduling users with high packet lost ratio under the condition of existing a certain extent of packet lost, takes the requirements of user packet service sensitive to the time delay jitter into full consideration, and controls the time delay jitter to maintain invariable, therefore improves the telecommunication quality of those users.
    • 本发明提供了一种在无线电信系统中调度分组的方法,其中要发送的用户分组队列被划分成具有丢失分组的用户分组队列,并且用户分组队列不丢失分组; 对于具有丢失分组的用户分组队列,如果用户的分组的实时丢失比率超过分组的预定丢失比率阈值,则终止与用户的连接; 如果用户的分组的实时丢失率不超过分组的预定丢失比率阈值,则根据分组的丢失比率的音量调度用户分组队列; 对于没有丢失分组的用户分组队列,根据分组长度,信道质量状态,时间延迟和时间抖动来调度。 本发明通过在存在一定程度的分组丢失的情况下优先调度具有高分组丢失率的用户来降低分组丢失率,充分考虑到用户分组业务对时延抖动的敏感性要求,并进行控制 时延抖动保持不变,因此提高了用户的电信质量。
