CONVERTER AND THE DRIVING METHOD THEREOF

摘要

A converter and a driving method thereof are provided to control the phase difference between a switching operation of a slave switch and the switching operation of a master switch to 180 degrees by estimating an intermediate point of one switching cycle of the master switch. A converter includes a first inductor(41), a second inductor(42), a capacitive element, a master switch(43), a slave switch(44), and a switch controller(30). The master switch delivers the current flowing in the first inductor to a capacitive element according to the switching operation. The salve switching delivers the current flowing in the second inductor to the capacitive element according to the switching operation. The switch controller includes a master controller and a slave controller. The master controller controls the switching operation of the master switch. The slave controller controls the switching operation of the slave switch.
