Ringing Suppression Method and Apparatus for Power Converters |
摘要 |
A method of controlling a power converter for converting a DC input voltage to a DC output voltage is presented The power converter comprises an inductor, one or more switching elements for energizing and de-energizing the inductor, a drive circuit for controlling switching operation of the one or more switching elements in accordance with a control signal, and a feedback circuit for generating the control signal on the basis of a first feedback quantity indicative of an actual output voltage of the power converter and in accordance with one or more circuit parameters of the feedback circuit, the method comprising: detecting an open loop condition of feedback control by the feedback circuit; and modifying at least one of the circuit parameters of the feedback circuit in such a manner that a time until the feedback control by the feedback circuit returns to the closed loop condition is reduced. |

1. A method of controlling a power converter for converting a DC input voltage to a DC output voltage, wherein the power converter comprises an inductor, one or more switching elements for energizing and de-energizing the inductor, a drive circuit for controlling switching operation of the one or more switching elements in accordance with a control signal, and a feedback circuit for generating the control signal on the basis of a first feedback quantity indicative of an actual output voltage of the power converter and in accordance with one or more circuit parameters of the feedback circuit, the method comprising:
detecting an open loop condition of feedback control by the feedback circuit; and modifying at least one of the circuit parameters of the feedback circuit in such a manner that a time until the feedback control returns to the closed loop condition is reduced. |
