CONTROL OF A SOFT-SWITCHED VARIABLE FREQUENCY BUCK REGULATOR |
| 摘要 |
A system and method are provided for controlling a soft-switched modified buck regulator circuit. A voltage (Vx) across or a current through a pull-down switching mechanism within the modified buck regulator circuit is sensed when the pull-down switching mechanism is enabled, where the pull-down switching mechanism is coupled to an upstream end of an inductor and is coupled in parallel with a capacitor. A target time when the pull-down switching mechanism will be disabled (tlf) is computed and the pull-down transistor is disabled at the computed target time. |

1. A method, comprising:
sensing a voltage (Vx) across or a current through a pull-down switching mechanism within a modified buck regulator circuit when the pull-down switching mechanism is enabled, wherein the pull-down switching mechanism is coupled to an upstream end of an inductor and is coupled in parallel with a capacitor; computing a target time when the pull-down switching mechanism will be disabled (tlf); and disabling the pull-down switching mechanism at the computed target time. |
