Inventor: ZHU ZHIPENG
IPC: H01M10/44
Filed: 2019-03-08
Abstract: An intelligent quick charge circuit for a lithium battery comprises a power supply circuit, a controller, and an energy storage circuit. The power supply circuit is connected to the controller and a power supply input. An output of the power supply circuit is connected to the energy storage circuit. An output of the energy storage circuit is connected to a rechargeable battery. A charge current measurement unit and a first charge voltage measurement unit are provided between the output of the energy storage circuit and the controller. A second charge voltage measurement unit is provided between the rechargeable battery and the controller. The controller controls the power supply circuit to store energy for the energy storage circuit and acquire a required charge current/voltage so as to perform trickle charging, constant-current charging, and constant-voltage charging on the rechargeable battery. During constant-current charging, the controller controls the power supply circuit and the energy storage circuit to store energy and acquire a second charge current, and uses the second charge current to perform constant-current charging on the rechargeable battery, until a charge voltage measurement of the first charge voltage measurement unit reaches a maximum safe charge voltage value. In addition, a battery voltage value of the second charge voltage measurement unit is maintained within a safe voltage range, such that a time required for completely charging the whole battery is reduced.

Title: Radio link monitoring reference signal resource reconfiguration
Inventor: CHENG PENG
IPC: H04W16/28
Filed: 2019-04-03
Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (HE) may support beam management to determine beams for communicating with a base station, measure characteristics of the beams, and periodically report the measurements to the base station. The beam management may include a beam failure recovery procedure, where the UE detects and resolves a beam failure with the base station. Additionally, the UE may perform radio link monitoring (RLM) on a set of reference signals configured by the base station to determine if a radio link (e.g,, beamformed transmission) is synchronized or not between the UE and base station. In some cases, these RLM reference signals (RLM-RSs) may be reconfigured, where the reconfiguration may be based on the periodic beam measurement reports for beam management, a beam monitoring event trigger, a beam failure recovery, or a combination thereof.

Abstract: Disclosed is a full-bridge synchronous rectification controller, in which a full-bridge synchronous rectification circuit formed by two self-driven PMOS synchronous rectifiers and two externally-driven NMOD synchronous rectifiers, and a control circuit thereof are integrated. The two self-driven synchronous rectifiers select to be turned on by transformer windings on their own, without requiring a driving circuit. The two externally-driven synchronous rectifiers generate a spike voltage at the drain after being turned on, and a synchronous rectification logic module 1 and a synchronous rectification logic module 2 may generate signals for turning off the externally-driven synchronous rectifiers after detecting the spike voltage, so a signal for turning off the externally-driven synchronous rectifiers is blocked by means of a minimum turn-on time signal, preventing the externally-driven synchronous rectifiers from being turned off immediately after being turned on. The present invention can realize that only one full-bridge synchronous rectification controller is required for a secondary side of a separately excited push-pull converter, improving the output efficiency, saving one secondary winding, improving the production efficiency, and reducing machining costs and power supply system costs.
