  • Control device for multiphase interleaved DC-DC converter and control method thereof
    Patent number: 9190909
    Abstract: This instant disclosure provides a control method for interleaved multiphase Boost PFC converter. The interleaved multiphase Boost PFC converter has a master phase and a plurality of slave phases, the master phase operates in the critical conduction mode, the master of each slave phase has an inductor and a power switch. The control method comprises, configuring the phase difference between each slave phase and the master phase; setting up each slave phase to operate in the critical conduction mode; monitoring the operating mode of each slave phase is in the continuous conducting mode, the discontinuous conducting mode, or the critical conduction mode when the system is disturbed; and adjusting the power switch on time of the slave phase according to the operating mode of the slave phase so as to make the slave phase return to operate in critical conduction mode.
