摘要： A method of controlling a power converter (20) of a motor drive system (10)controls the power converter (20) during a first operating mode by applying a current control scheme, which sets power converter commands to control torque current flowing from the power converter (20) to the motor (30) to achieve desired motor speed; and initiates a second operating mode when power supply to the power converter (20) is interrupted. The second operating mode includes controlling negative torque current between the power converter (20) and the motor (30) so that mechanical energy from the motor (30) charges an element (58) on a power supply side of the power converter (20). The first operating mode is resumed when the input power recovers. Torque current between the power converter (20) and the motor (30) is also controlled to limit a maximum transient DC bus voltage.

摘要： A method and apparatus control a power converter (20) of a motor drive system. The power converter (20) is controlled during a first operating mode by applying a current control scheme, which sets power converter commands to control active and reactive current components flowing from the power converter (20) to the motor (10) to achieve desired motor speed; and a fault protection scheme is executed during a second operating mode. The fault protection scheme generates power converter commands to reduce the active current component flowing from the power converter (20) to the motor (10) is substantially zero. The first operating mode will be resumed upon receiving the restart command if the motor speed is above a pre-set shutdown threshold.

摘要： A filter apparatus and distributor plate therefor of the quick-change type which are easily fabricated from plastic material by injection molding are disclosed. The distributor plates which are flangeless can accommodate one, two, three or more canisters. The canisters which are neckless have two prong-like arcuate member with flanges. The prong-like members extend through the distributor plate and the canisters are secured to the distributor plate by locking knobs which have mating flanges for engaging the flanges on the prong-like members. Opposing ports in the canisters and distributor plate are seal by O-rings which are housed on the flat top surface of the canisters. For filter apparatuses having more than one canister, the distributor is preferably made in two parts, namely a main body part and an insert part which are bonded into a single unitary part by sonic welding. Since the filter apparatuses of this invention have canisters that do not have necks, problems associated with seals around ports on necks are circumvented. Likewise, since the filter apparatuses of this invention have distributor plates that do not have flanges, problems associated with damage to flanges on distributor plates are circumvented. The plate-like configuration of the distributor plates and locking knobs facilitate injection molding and reduce the amount of plastic required and post injection molding machining.
摘要翻译：公开了一种通过注射成型容易地由塑料材料制成的快换式过滤装置和分配器板。无法兰的分配器板可容纳一个，两个，三个或更多的罐。无颈的罐具有两个带法兰的叉状弓形构件。叉状构件延伸穿过分配器板，并且通过具有用于接合叉形构件上的凸缘的配合凸缘的锁定旋钮将罐固定到分配器板。罐和分配器板中的相对的端口由容纳在罐的平坦顶表面上的O形环密封。对于具有多于一个罐的过滤装置，优选地，分配器由两部分组成，即主体部分和插入部分，其通过声波焊接结合成单个整体部分。由于本发明的过滤装置具有不具有颈部的罐，所以与颈部端口处的密封相关的问题被避开。同样地，由于本发明的过滤装置具有不具有凸缘的分配器板，所以与分配器板上的凸缘的损坏有关的问题被避开。分配器板和锁定旋钮的板状构造便于注射成型，并减少所需的塑料和后注塑成型加工量。
