Patent number: 10601250Abstract: A half bridge power converter can be coupled to, or included in, a wireless transmitter device. The half bridge power converter includes an upper switching element connected between a direct current supply voltage and a lower switching element. A duty controller is coupled to the upper and the lower switching elements and is configured to asymmetrically control the duty cycles of the upper and lower switching elements based on a voltage level of the direct current supply voltage. In general, the duty cycle of the lower switching element is different than the duty cycle of the upper switching element. Additionally or alternatively, the duty controller is configured to determine and control the duty cycles of the upper and lower switching elements to adjust a direct current gain of a wireless energy transfer system that includes the wireless transmitter device.Type: GrantFiled: March 31, 2017Date of Patent: March 24, 2020Assignee: APPLE INC.Inventors: InHwan Oh, Shimon Elkayam, Manisha P.

Patent number: 9490644Abstract: During operation, the DC converter and a DC battery charger controller in a charger circuit transitions from a first error signal to a second error signal for use in charging a battery, wherein the first error signal and the second error signal, respectively, correspond to feedback sources in a plurality of feedback sources with a plurality of feedback sources. Then, the DC converter and a DC battery charger controller selects a gain and an impedance to ground of a damping circuit based on the selected second error signal, where the damping circuit applies the gain and the impedance to ground to the second error signal. Moreover, the DC converter and a DC battery charger controller selects one or more clamping voltages of a voltage-clamping circuit based on the selected second error signal, where the voltage-clamping circuit applies the one or more clamping voltages to an output from the damping circuit.Type: GrantFiled: September 9, 2014Date of Patent: November 8, 2016Assignee: Apple Inc.Inventors: Arthur H.

Patent number: 9134775Abstract: The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current.Type: GrantFiled: May 22, 2012Date of Patent: September 15, 2015Assignee: Apple Inc.Inventors: Mao Ye, Bharatkumar K.

Publication number: 20150069956Abstract: A charger circuit includes an interface connector that may be coupled to a power adapter that provides an input signal having an input voltage, and a buck-boost converter circuit that may be coupled to a battery having a charging voltage. At a given time, the buck-boost converter circuit operates in a mode in a group of modes based on a control signal, where the group of modes may include at least a buck mode and a boost mode. In particular, the charger circuit includes control logic that generates the control signal based on the charging voltage and a charging capability of the power adapter. Thus, if the charging voltage suitably exceeds the input voltage, the buck-boost converter circuit may operate in the boost mode. However, if the charging voltage is approximately less than or equal to the input voltage, the buck-boost converter circuit may operate in the buck mode.Type: ApplicationFiled: September 9, 2014Publication date: March 12, 2015Inventors: Yongxuan Hu, Shimon Elkayam, Collin E.
