  • Patent number: 11937293
    Abstract: This disclosure relates generally to wireless communications and, more particularly, to systems and methods for determining an adaptive random access response window length in non-terrestrial networks. In one embodiment, a method performed by a communication device includes: receiving system information from a communication node, wherein the communication node communicates using a satellite in orbit or a high altitude platform station (HAPS); and determining an adaptive random access response window length based on the system information and whether the communication device has access to situation information that: characterizes a location of the communication device, an ephemeris of the satellite or a trajectory of the HAPS, and a payload type of the satellite or the HAPS.

  • Publication number: 20230074022
    Abstract: Power converters with power factor correction circuits and controllers thereof that are configured to generate frequency-adjustable first and second pulsed signals having respective and complementary phases separated by an adjustable deadtime. For example, a power converter may be configured to receive an alternating current (AC) input signal and output a direct current (DC) output signal. The power converter may include at least one DC/DC converter and a power factor correction circuit. The power factor correction circuit may include a first switching transistor comprising a first gate; a second switching transistor in series with the first switching transistor and comprising a second gate; and a controller configured to generate first and second pulsed signals having respective and complementary phases and separated by an adjustable deadtime and apply the generated first and second pulsed signals to the first and second gates, respectively.

  • Publication number: 20230071003
    Abstract: Power factor correction circuits and controllers thereof that are configured to generate frequency-adjustable first and second pulsed signals having respective and complementary phases separated by an adjustable deadtime. For example, a controller for a power factor correction circuit may include a comparator, a frequency controller, and a deadtime controller. The controller may be configured to: receive an input signal comprising a measured output voltage of the power factor correction circuit; compare, via the comparator, the measured output voltage with a set point, resulting in a difference between the measured output voltage and the set point; feed the difference into the frequency controller and adjust a frequency of the first and second pulsed signals based on an output of the frequency controller; and provide the difference to the deadtime controller and adjust the deadtime of the first and second pulsed signals based on an output of the deadtime controller.
