Closed-loop digital control system for a DC/DC converter
First Claim
Patent Images
1. A control system comprising:
- a DC/DC converter that includes a first inductance and a second inductance, that receives a first DC voltage, and that generates a second DC voltage;
a control module that;
charges said first inductance while discharging said second inductance during a first mode; and
one of charges and discharges both of said first and second inductances during a second mode; and
an output capacitance,wherein said control module selects said second mode based on a transient condition and current through said output capacitance, and detects said transient condition when said current through said output capacitance is one of greater than a first predetermined current and less than a second predetermined current.

Abstract
A control system comprises a DC/DC converter that includes first and second inductances, that receives a first DC voltage and that generates a second DC voltage. A control module selectively charges or discharges the first inductance while discharging or charging the second inductance during a first mode and one of charges both of the first and second inductances or discharges both of the first and second inductances during a second mode.
