    • A method and apparatus for welding with an engine driven inverter power supply includes generating an ac output with an engine and generator. The output is rectified and inverted to provide an ac inverter output. The engine is controlled using feedback indicative of a welding output operating parameter. The feedback may also be taken from the inverter or generator, and the generator may be controlled instead of or in addition to the engine. Engine parameters that may be controlled include engine speed, selecting between an idle speed and a run speed, a throttle position, a fuel pump, an injection timer, a fuel to air ratio, fuel consumption and ignition timing. Another aspect of the invention is having the feedback be responsive to one or more of the welding current, welding voltage, welding power, or functions thereof. The feedback may be responsive to the current, voltage, power, ripple and functions thereof. An aux power output is derived directly from the generator and feedback from the aux load is used to determine if the engine should be idling or running at high speed.
    • 一种用发动机驱动的逆变器电源进行焊接的方法和装置,包括用发动机和发电机产生交流输出。 输出整流和反相,提供交流逆变器输出。 使用反馈表示焊接输出操作参数来控制发动机。 也可以从逆变器或发电机获取反馈,并且发动机可以被控制而不是发动机或除了发动机之外。 可以控制的发动机参数包括发动机转速,怠速和运行速度之间的选择,节气门位置,燃料泵,喷射定时器,燃料空气比,燃料消耗和点火正时。 本发明的另一方面是使反馈响应于焊接电流,焊接电压,焊接功率或其功能中的一个或多个。 反馈可以响应于电流,电压,功率,纹波和功能。 辅助功率输出直接来自发电机,来自辅助负载的反馈用于确定发动机是否应空转或高速运行。

    • A weighted round-robin arbitrator for a plurality of data queue includes an arbitration table comprising a plurality of entries. Each entry represents a time slot for the transmission of one data packet from a selected one of the plurality of data queues. There is one arbitration logic circuit for each of the plurality of entries in the arbitration table. Each arbitration logic circuit includes a first multiplexer receiving an output from a first table entry and an output from a second table entry in the arbitration table. A second multiplexer receives empty flags from each of the data queues, the flags indicating that there is no data to the sent from that queue. An output of the second multiplexer is coupled to a control input of the first multiplexer so that the first table entry value is output from the first multiplexer if the corresponding queue has data to be sent out and the second table entry value is sent out from the first multiplexer if the queue corresponding to that table entry has data to be sent out and the queue corresponding to the first entry has no data to be sent out.
    • 用于多个数据队列的加权轮询仲裁器包括包括多个条目的仲裁表。 每个条目表示用于从多个数据队列中选择的一个数据队列传输一个数据包的时隙。 仲裁表中的多个条目中的每一个都有一个仲裁逻辑电路。 每个仲裁逻辑电路包括接收来自第一表条目的输出的第一多路复用器和仲裁表中的第二表条目的输出。 第二个多路复用器从每个数据队列接收空标志,标志指示从该队列发送的数据没有数据。 第二多路复用器的输出被耦合到第一多路复用器的控制输入,使得如果对应的队列具有要发送的数据并且从第一多路复用器发送第二表条目值,则从第一多路复用器输出第一表条目值 第一复用器如果对应于该表项的队列具有要发送的数据,并且对应于第一条目的队列没有要发送的数据。
