Abstract

The present invention provides a controller and a power converter and a method of controlling the power converter. The controller includes: a control terminal for providing a control signal to control a transformer circuit in the power converter, wherein each cycle of the control signal includes a first time interval and a second time interval; and connected to the control a control circuit at the terminal for increasing the primary current flowing through the primary coil of the transformer circuit and increasing the secondary current flowing through the secondary coil of the transformer circuit during the first time interval, during the second time interval The increase in the primary current is terminated within the interval, and the first time interval is controlled such that the first time interval is inversely proportional to the input voltage supplied to the primary coil. The present invention can reasonably control the output of the power converter.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a controller, a power converter and a method for controlling the power converter. Background technique [0002] figure 1 is a schematic circuit diagram of an existing DC / DC converter 100 . The DC / DC converter 100 includes a transformer 102 and a switch SW0 connected in series with the primary coil of the transformer 102 . The control signal 106 controls the output power of the DC / DC converter 100 by controlling the switch SW0. For example, the control signal 106 connects the primary winding of the transformer 102 to a power source, such as a DC voltage V DC , so that there will be a primary current I P flows through the primary winding of the transformer 102 . Correspondingly, the secondary current I S The current flows through the secondary coil of the transformer 102 and through the inductor L, and flows to the output terminal of the DC / DC converter 100 . At the same time, th...
