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 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.

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： An external heat exchanger is used to transfer heat from a compressor lubricant to an expanded working fluid, thereby cooling the lubricant. The heat exchanger may also be used to sub-cool condensed working fluid with the same flow of expanded working fluid. A horizontal scroll-type compressor includes an intermediate lubricant sump between a main bearing support and a scroll member. A counterweight on the crankshaft can travel through the lubricant in the intermediate sump to splash the lubricant around. A horizontal scroll-type compressor can include multiple machined surfaces that are utilized to precisely center and align components of the compressor.
