Abstract
A power converter is described that includes a switch. The power converter may also include a controller that controls the switch. The controller may be configured to ascertain a first parameter. Additionally, the controller may be configured to ascertain a second parameter. The controller may dynamically modulate duty cycle of the switch based on the first parameter and the second parameter in addition and independent of the control loop.
Claims20
A power converter comprising:
- a switch;
- and
- a controller configured to:
- ascertain at least a first parameter;
- ascertain at least a second parameter;
- and
- dynamically modulate a duty cycle of the switch using one or more of pulse-width-modulation, pulse-duration modulation, or pulse-density-modulation based on at least the first parameter and the second parameter and independent of a control loop.
4 more elements
A method comprising:
- ascertaining at least a first parameter;
- ascertaining at least a second parameter;
- and
- dynamically modulating a duty cycle of a switch controlling a power converter using one or more of pulse-width-modulation, pulse-duration modulation, or pulse-density-modulation, based on at least the first parameter and the second parameter and independent of a control loop.
1 more element
A power converter comprising:
- means for switching;
- means for ascertaining at least a first parameter;
- means for ascertaining at least a second parameter;
- and
- means for dynamically modulating a duty cycle of the means for switching based on at least the first parameter and the second parameter independent of a control loop.
