A Novel SFVM-M$^{\bm 3}$ Control Scheme for Interleaved CCM/DCM Boundary-Mode Boost Converter in PFC Applications

This paper presents an open-loop synchronized-OFF voltage-mode Master-made-modulated (SFVM-M 3) control scheme for a two-phase interleaved boost converter with Master-Slave strategy for power factor correction applications. Interleaving the continuous-conduction-mode and discontinuous-conduction-mode (CCM/DCM) boundary-mode boost converters, however, is complicated because of the variable-frequencies nature of the operation. Furthermore, a problem of current divergence is implied in the Slave converter. In this paper, an ON-time tuning scheme of Slave converter is presented to stabilize the interleaved converter without using a phase-lock loop, or multiplier and current sensors. It can be implemented not only by an analog circuit, but also an alternative approach, which is calculated by a digital processor such as DSP. In the following discussion, an analog circuit will be proposed to generate the M3 control signal and verify the stability of interleaved boost converter with SFVM-M 3 control scheme, and then a digital implementation will be proposed to design the SFVM-M3 controller.
