Dc/Dc Converter With Magnetic Flux Density Limits

US Patent:
2011029, Dec 8, 2011
Filed:
Jun 2, 2011
Appl. No.:
13/151689
Inventors:
William Hall Coley - Cary NC, US
Charles Edward Hawkes - Cary NC, US

Assignee:
LINEAR TECHNOLOGY CORPORATION - Milpitas CA
International Classification:
H02M 3/335
US Classification:
363 2109
Abstract:
A DC/DC converter may include a power stage circuit, a pulse generator circuit, a flux density monitor, and power control logic. The power stage circuit includes an input, an output, and a transformer with a core. The power stage circuit may be configured to operate in a power transfer mode during which power is transferred from the input to the output and a reset mode during which flux density in the core of the transformer is reduced. The pulse generator circuit may be configured to generate pulses that regulate the output of the power stage circuit. The flux density monitor circuit may be configured to generate flux density information indicative of the flux density of the core of the transformer during both the power transfer mode and the reset mode. The power stage control logic may be configured to regulate the output of the power stage circuit based on the pulses and to prevent the core of the transformer from saturating based on the flux density information.
