The disclosure relates to compressors for heat exchange systems, heat exchange systems having such compressors, and methods for controlling operation of compressors. The compressor includes a drive device for driving the compressor and having at least a first and second working conditions. An output power of the drive device under the second working condition is greater than an output power under the first working condition. The compressor has at least one upload/download flow path configured to be opened before the drive device is switched from the first working condition to the second working condition to reduce a suction flow of the compressor until current operating parameters of the compressor reach preset values, after which the switching is performed, and to increase the suction flow until the compressor is in a required working state, after the switching is completed.

The input circuit is configured to provide, via the third output pin, a voltage signal.

Diagnostic system

Apparatus and associated methods relate to high accuracy timestamp support by controlling a first phase relationship between an outbound signal transmitted by a transmitting circuit and a local reference clock signal, measuring a second phase difference between a received data signal and the local reference signal, and measuring a third phase difference between a received time of day (RXTOD) signal and the local reference signal. In an illustrative example, a state machine circuit may be operated to control the first phase relationship, a phase measuring circuit may be configured to measure the second phase difference and the third phase difference. By comparing results obtained from phase control and phase measurement, the time of day (TOD) of each transmitted/received bit can be calculated at 1-bit level accuracy and achieve 1-bit level accuracy in the timestamp.

The present disclosure relates to a superposed signal sampling apparatus, including: a signal receiving module, a signal extracting module, and a signal output module. The signal receiving module is used to receive a superposed signal. The signal extracting module is used to determine whether the received superposed signal is within a preset threshold range of a direct current signal; if the received superposed signal is within the threshold range, extract a previously received signal as a direct current signal to be output; and if the received superposed signal is beyond the threshold range, extract a currently received signal as a direct current signal to be output. The signal output module is used to integrate the direct current signal extracted by the signal extracting module, and then output the direct current signal. The present disclosure further relates to a superposed signal sampling method.
