Fixed Frequency Hysteretic Regulator

View page
US Patent:
6885175, Apr 26, 2005
Filed:
Oct 24, 2003
Appl. No.:
10/693701
Inventors:
Alex Mihalka - Livermore CA, US
Assignee:
International Rectifier Corporation - El Segundo CA
International Classification:
G05F001/40
US Classification:
323282
Abstract:
A control circuit for controlling a hysteretic regulator to operate at substantially fixed frequency has a voltage offset circuit which receives a first feedback signal and generates a pair of upper and lower offset voltages; a control reference stage which receives a reference voltage and the upper and lower offset voltages and outputs upper and lower control reference voltages; and a window comparator which receives the upper and lower control reference voltages and an output voltage feedback signal and outputs a pair of upper and lower control voltages for controlling switching of the hysteretic regulator at a fixed frequency. The first feedback signal may be representative of a switching frequency, a temperature or an output voltage of the hysteretic regulator, for example. The voltage offset circuit may further receive a second and/or an additional feedback signal. The first, second and/or additional feedback signals further may be weighted.

Digital Multiphase Control System

View page
US Patent:
7109694, Sep 19, 2006
Filed:
Jul 14, 2004
Appl. No.:
10/890674
Inventors:
Alex Mihalka - Livermore CA, US
Assignee:
International Rectifier Corporation - El Segundo CA
International Classification:
G05F 1/46
US Classification:
323283
Abstract:
A multi-phase control system for a power supply provides a data bus between a controller and multiple phase drivers to obtain a synchronous control through a flexible and non-dependent control configuration. The controller provides data signals to the data bus that is connected to the various phase drivers, with the data signals dependent upon a switching frequency and ON/OFF command signals for a particular phase. Each of the phase drivers have decoding logic for receiving the data signals over the data bus, as well as independent selection or addressing logic for choosing the phase driver to react to the data signals on the data bus. A variety of control configurations may be realized according to this control technique including resetting all drivers, setting all phases to ON or all phases to OFF conditions, skipping phase activation and so forth. The flexible control permits output current sharing to be controlled among the various phases to provide a desired output current for the power supply. The control configuration permits fast and robust response to transient conditions while providing a simplified control in an N phase system over a data bus that can vary between 1 and M lines.

Capacitor Charging Fet Switcher With Controller To Adjust Pulse Width

View page
US Patent:
45861188, Apr 29, 1986
Filed:
Jun 5, 1984
Appl. No.:
6/617651
Inventors:
Alex M. Mihalka - Livermore CA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
H02M 3337
H02H 7122
US Classification:
363 17
Abstract:
A switching power supply includes an FET full bridge, a controller to drive the FETs, a programmable controller to dynamically control final output current by adjusting pulse width, and a variety of protective systems, including an overcurrent latch for current control. Power MOSFETS are switched at a variable frequency from 20-50 kHz to charge a capacitor load from 0 to 6 kV. A ferrite transformer steps up the DC input. The transformer primary is a full bridge configuration with the FET switches and the secondary is fed into a high voltage full wave rectifier whose output is connected directly to the energy storage capacitor. The peak current is held constant by varying the pulse width using predetermined timing resistors and counting pulses. The pulse width is increased as the capacitor charges to maintain peak current. A digital ripple counter counts pulses, and after the desired number is reached, an up-counter is clocked.
