Abstract:
A power converter and a dead-time controller for a power converter. The power converter includes a first power switching element through which an input voltage is applied, a second power switching element connected to the first power switching element through a switching node, an output circuit coupled to the switching node, a control switching element configured to control the first power switching element and the second power switching element through a first control node connected to the first power switching element and a second control node connected to the second power switching element, and a control assist unit configured to control the control switching element on the basis of voltages of the switching node and the first control node or voltages of the switching node and the second control node.

Claim (Index 14):
A dead-time controller configured to control a dead-time of a power converter including a first power switching element through which an input voltage is applied, a second power switching element coupled to the first power switching element through a switching node, and an output circuit coupled to the switching node, the dead-time controller comprising:\n a control switching element configured to control the first power switching element and the second power switching element through a first control node connected to the first power switching element and a second control node connected to the second power switching element; and a control assist unit configured to reduce a dead-time, which is generated by the control switching element, between the first power switching element and the second power switching element on the basis of a voltage of the switching node and a voltage of the first control node or to control the control switching element on the basis of a voltage of the switching node and a voltage of the second control nod; wherein the control assist unit includes a first assist module and a first assist transistor, wherein the first assist module is enabled in synchronized with a voltage of the switching node, which is changed to a low state, and the enabled first assist module turns the first assist transistor on, thereby turning the second power switching element on, wherein the control assist unit further includes a second assist module and a second assist transistor, and wherein the second assist module is enabled according to the voltage of the switching node in the low state and outputs a high value when the voltage of the second control node is low to turn the second assist transistor on, thereby turning the first power switching element on.
