Method and system for operating a power converter
First Claim
1. A method for operating a power converter comprising an electrical component, a first switch coupled to a first voltage source, and a second switch coupled to a second voltage source, the method comprising:
- receiving a signal representative of a desired current flow through the electrical component;
generating a signal representative of a difference between the desired current flow and an actual current flow through the electrical component;
calculating a first duty cycle for the first switch based on the signal representative of the difference and a first voltage generated by the first voltage source; and
calculating a second duty cycle for the second switch based on the signal representative of the difference and a second voltage generated by the second voltage source.

Abstract
A method and system for operating a power converter having an electrical component and a switch coupled to a voltage source are provided. A signal is received that is representative of a desired current flow through the electrical component. A signal is generated that is representative of a difference between the desired current flow and an actual current flow through the electrical component. A duty cycle for the switch is calculated based on the signal representative of the difference and a voltage generated by the voltage source.
