Abstract :
This paper investigated a novel PWM scheme for two-phase interleaved boost converter with voltage multiplier by combining Alternating Phase Shift (APS) and traditional interleaving PWM control. The APS control is used to reduce the voltage stress on switches in light load while the traditional control is used to keep better performance in heavy load. The boundary condition for swapping between APS and traditional interleaving PWM control is derived. Simulation and experimental results prove the analysis.
