Abstract
Abstract Bang or bang-bang control is applied to interleaved power converters. With the bang control on, oscillator signals applied to the power converters are overridden in order to change the power output of both power converters. When the override is removed, both oscillating signals continue from points in their cycles at which they were overridden. An oscillator may be frozen during override by interrupting the charging and discharging of a capacitor in the oscillator.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
100 words
A method of power conversion comprising: applying a first oscillator signal to a first power converter to provide a first power to an output; applying a second oscillator signal, out of phase with respect to the first oscillator signal, to a second power converter to provide a second power to the output; overriding the first and second oscillator signals to change the power output of both power converters to correct the output; and removing override of the first and second oscillator signals and continuing the first and second oscillating signals from points in their cycles at which they were overridden.
Claim 2
Independent Claim
100 words
A method of power conversion comprising: applying a first oscillator signal to a first power converter to provide a first power to an output; applying a second oscillator signal, out of phase with respect to the first oscillator signal, to a second power converter to provide a second power to the output; overriding the first and second oscillator signals to change the power output of both power converters to correct the output; and removing override of the first and second oscillator signals and continuing the first and second oscillating signals from points in their cycles at which they were overridden.
Claim 3
Dependent Claim
14 words
