Abstract: Described herein are systems and methods that allow for correcting a residual frequency offset in the GHz frequency range by using low-complexity analog circuit implementations of a broad-band frequency detector that comprises two analog polyphase filters in a dual configuration. Each filter comprises an RC network of cross-coupled capacitors that facilitate filters with opposite passbands and opposite stop-bands. In various embodiments, the outputs of the two filters are combined to obtain power metrics that when subtracted from each other, deliver a measure of the imbalance between the positive and negative halves of a frequency spectrum. Since the measure is substantially proportional to a frequency offset within a linear range spanning 5 GHz or more, the polyphase filters may be used in a broad-band frequency detector that, based on the measure, adjusts the frequency offset.

Abstract: A method for suppressing a common mode impulse current for an inverter generated when an alternating current switch is switched on and a device for applying the method are provided. Before the alternating current switch is switched on for the inverter, a target value of a common mode voltage between the inverter and ground is calculated based on at least one of a voltage between an alternating current port and ground, a voltage between the inverter and ground and a voltage across the alternating current switch sampled in real time. Then, a compensation power supply arranged between a main circuit of the inverter and ground is controlled to change the common mode voltage to the target value, so that a common mode voltage difference between two ends of the alternating current switch is zero. Subsequently, the inverter is controlled to switch on the alternating current switch.
