US Patent:

20130063101, Mar 14, 2013

Filed:

Apr 3, 2012

Appl. No.:

13/438268

Inventors:

Hrishikesh Ratnakar NENE - Stafford TX, US

Assignee:

TEXAS INSTRUMENTS INCORPORATED - Dallas TX

International Classification:

G05F 1/10
H03M 1/20

US Classification:

323234, 341131

Abstract:

A system and method for controlling a power converter includes a digital-to-analog converter (DAC) and ramp generator for generating a reference current command. The DAC is configured to decrement (or increment) to a next state after a fixed number of clock pulses have occurred. The reference current command controls an output of the power converter. Means are provided for delaying an output of the DAC for a number of clock pulses less than the fixed number to increase a resolution of the DAC.

Appl. No.:

16/424248

Inventors:

- Dallas TX, US
Hrishikesh Ratnakar Nene - Katy TX, US

International Classification:

H02M 3/335
H02M 1/084
H02M 3/337

Abstract:

One example includes an interleaved resonant converter circuit. The circuit includes a plurality of resonant converter circuits that are each coupled to an output node and are configured to collectively generate an output voltage on the output node in response to a respective plurality of sets of switching signals at each of a respective plurality of phases. The circuit also includes a switching controller configured to generate each of the plurality of sets of switching signals having a variable duty-cycle relative to each other at each of the plurality of phases.

Appl. No.:

15/427694

Inventors:

- Dallas TX, US
Hrishikesh Nene - Katy TX, US

International Classification:

H02M 3/335
H02M 1/08

Abstract:

A selected-parameter adaptively switched power conversion system, for example, includes a counter for determining a period of an output oscillation a power supply switch, where the output oscillation starts when an output current generated by stored power of the power supply coil decays substantially to zero. An event generator for generating a switching delay event in response to the determined output oscillation period and generates a switching delay event in response to a determination of a phase of the output oscillation.

Assignee:

TEXAS INSTRUMENTS INCORPORATED - Dallas TX

International Classification:

G05F 1/10

US Classification:

323234

Abstract:

An apparatus and a method to control peak current mode controlled power converter system using selective noise blanking are disclosed. The control of the peak current mode controlled power converter system using selective noise blanking is implemented by hardware, software and/or combination of both to carry out adjusting a blanking time and a blanking time period to prevent change of an output of a pulse modulated waveform generator starting at the blanking time for the blanking time period.
