Patent number: 10153695Abstract: Embodiments described herein describe a switching power converter that includes a switch, an inductor, a diode, and a controller that generates a control signal to turn on and turn off the switch. The controller generates the control signal by generating a reference signal, integrating a difference between a voltage value of the generated reference signal, and a voltage difference between voltage values of the switching node and the second output terminal, and generating the control signal by processing the integrated voltage difference.Type: GrantFiled: June 20, 2017Date of Patent: December 11, 2018Assignee: Dialog Semiconductor Inc.Inventor: Andrey B.

Patent number: 9998013Abstract: A power supply can be operated in a low power mode by adjusting the pulses provided to a power supply switch until a pulse resulting in a reduced amount of power that exceeds a minimum power threshold required by a load coupled to the power supply switch is identified. For each successive switching cycle, a pulse causing a lower power to be provided to the load is produced. When a pulse is produced that causes a power to be provided to the load that does not exceed the minimum power threshold required by the load, a subsequent pulse is produced that causes a greater power to be provided to the load than the previous pulse. If the greater power exceeds the minimum power threshold, the subsequent pulse is stored and similar pulses are provided for the remainder of the low power mode.Type: GrantFiled: May 1, 2015Date of Patent: June 12, 2018Assignee: Dialog Semiconductor Inc.Inventor: Andrey B.

Patent number: 9912142Abstract: One embodiment of a disclosed cable protection device connected between the positive and negative wires of the cable that provides an efficient method of protection from overheating of the device due to changes in temperatures with minimal power dissipation. The cable protection device includes a temperature monitoring device that continuously senses the temperature of the cable and device to check for overheating. A controller connected to the temperature monitor sends out an alarm message and a control signal to either an actuator circuit or a crowbar function circuit. The actuator circuit can send out current pulses to the adapter indicating the adapter to lower its current limit, so that the device can still keep charging and is not over heated. The crowbar function circuit causes the adapter to turn off power to the cable in order to provide burning of the device or connector due to overheating.Type: GrantFiled: April 30, 2015Date of Patent: March 6, 2018Assignee: Dialog Semiconductor, Inc.Inventors: Athar Zaidi, Andrey B.

Patent number: 6979980Abstract: There is provided by this invention soft switching interleaved power converters that are suitable for high power and high voltage applications such as plasma processing. They have greatly reduced switching losses and diode reverse-recovery losses which allows operation at high switching frequencies. The peak values of the reverse-recovery currents of the diodes are substantially less then their peak forward operating currents. The power converters incorporate power converter cells that comprise a plurality of switching assemblies that are operated with an interleaved switching pattern, and that are each connected to an input terminal of an inductor assembly that also has a common terminal. The inductance between each pair of input terminals is less than the inductance between each input terminal and the common terminal of the inductor assembly.Type: GrantFiled: August 24, 2004Date of Patent: December 27, 2005Assignee: Advanced Energy Industries, Inc.Inventors: Bryce L.
