Patent number: 8829879Abstract: A system includes an estimation module and a current measuring module. The estimation module estimates current through an inductor in an output stage of a power supply using a model of the current and generates an estimated current. The current measuring module measures the current through the inductor and generates a measured current. The estimation module adjusts the model based on the measured current.Type: GrantFiled: April 16, 2012Date of Patent: September 9, 2014Assignee: Maxim Integrated Products, Inc.Inventors: Paul Walker Latham, II, Mansur Kiadeh, Stewart Gall Kenly

Patent number: 8805554Abstract: A notch filter includes first, second, and third difference modules, a delay module, and a gain module. The first difference module calculates a first difference between a control signal in a pulse width modulation (PWM) system and a feedback value. The second difference module calculates a second difference between the first difference and a delayed second difference. The delay module generates the delayed second difference by introducing a one period delay to the second difference, wherein the period is based on a Nyquist frequency of the control signal. The gain module generates the feedback value by applying a gain to the delayed second difference. The third difference module generates a filtered control signal by calculating a difference between the signal and the feedback value, wherein the filtered control signal is used to control an operating parameter of the PWM system.Type: GrantFiled: August 18, 2011Date of Patent: August 12, 2014Assignee: Maxim Integrated Products, Inc.Inventors: Paul Walker Latham, II, Stewart Gall Kenly, II, Mansur Kiadeh

Patent number: 8564267Abstract: A system includes an input selection module, a multiplier selection module, a multiplier module, an adding module, a plurality of accumulators, and an estimation module. The input selection module selects input signals including a duty cycle signal and current and voltage signals of a power supply. The multiplier selection module selects inputs from sine and cosine generator. The multiplier module multiplies the selected input signals by the inputs from the sine and cosine generator to generate products. The adding module adds the products to generate sums. The plurality of accumulators accumulates the sums. The estimation module estimates values of a plurality of components including an inductance, a capacitance, and a resistance of the power supply based on the sums accumulated in the plurality of accumulators.Type: GrantFiled: August 26, 2011Date of Patent: October 22, 2013Assignee: Maxim Integrated Products, Inc.Inventors: Paul Walker Latham, II, Mansur Kiadeh, Siwas Chandhrasi, Stewart Gall Kenly, Andras Fekete

Patent number: 8159205Abstract: A system includes an averaging module, a high pass filter module, a first estimation module, a sensing module, and a combining module. The averaging module receives an output voltage of a power supply and that generates an average output voltage. The high pass filter module receives an average switching voltage used to control switches in an output stage of the power supply and filters a difference between the average output voltage and the average switching voltage. The estimation module estimates a first filtered current through an inductor in the output stage based on an output of the high pass filter module. The sensing module senses voltage across the inductor and estimates a second current through the inductor. The low pass filter module filters the second current. The combining module combines the first filtered current and the second filtered current to generate an estimated current through the inductor.Type: GrantFiled: December 3, 2010Date of Patent: April 17, 2012Assignee: Maxim Integrated Products, Inc.Inventors: Paul Walker Latham, II, Mansur Kiadeh, Stewart Gall Kenly
