摘要： A switching power converter (200, 300, 400, 500) comprises a transformer (211) with a parasitic capacitance (212), a first switch (207) coupled to the transformer (211) and configured to couple or decouple a load (219) to or from a power source via the transformer (211), a switch controller (205) coupled to the first switch (207) and configured to generate a switch drive signal (206) for turning on or off the first switch (207) according to switching cycles, and a bypass circuit configured to provide a bypass path for the parasitic elements such as the parasitic capacitance (212). The bypass circuit may be coupled in parallel with the auxiliary winding (220), the primary winding (213), or the secondary winding (214) of the transformer (211). High frequency ringing and EMI/RFI is reduced when the bypass circuit is enabled.

摘要： A compressor may include a shell, first and second scroll members, a partition and a first annular seal. The partition may be fixed to the shell and may overly the first scroll member. The partition may include first and second sides having a second discharge opening passing therethrough and being in communication with the first discharge opening. The first side may include a protrusion extending toward the first scroll member and generally surrounding the second discharge opening. The first annular seal may sealingly engage the partition and may be displaceable radially inward to a position abutting the protrusion to limit a radially inward travel of the first annular seal.
摘要翻译：压缩机可以包括壳体，第一和第二涡旋构件，隔板和第一环形密封件。分隔件可以固定到壳体并且可以过度地覆盖第一涡旋构件。分隔件可以包括具有穿过其中并与第一排出口连通的第二排放口的第一和第二侧。第一侧可以包括朝向第一涡旋构件延伸并且大致围绕第二排出口的突起。第一环形密封件可以密封地接合隔板，并且可以径向向内移动到与突起抵接的位置以限制第一环形密封件的径向向内的行进。

摘要： A compressor may include a shell and a housing fixed within the shell. A compression mechanism may be supported by the housing and may include an orbiting scroll member and a non-orbiting scroll member that are meshingly engaged to form a series of compression pockets. A retaining assembly may include an axial retention member and a rotational retention member, each of which is engaged with the non-orbiting scroll member to limit axial translation and rotation of the non-orbiting scroll member relative to the housing.

摘要： A scroll compressor includes a housing, a non-orbiting scroll member including a first spiral wrap, and an orbiting scroll member including a second spiral wrap. The first and second spiral wraps are interleaved to define at least one moving fluid pocket that decreases in size as it moves from a radially outer position to a radially inner position. A vapor-injection system may include a shell fitting in fluid communication with a fluid passageway of the non-orbiting scroll member via a vapor injection tube. The vapor injection tube may be fixed for movement with the non-orbiting scroll member for communicating vapor into the moving fluid pockets.
