  • Realizing ZVS and ZCS in a CCM boost converter with BCM control with a single switch
    Patent number: 10361619
    Abstract: Realizing ZVS and ZCS in a CCM Boost Converter with BCM control with a single switch. Embodiments disclosed herein relate to continuous conduction mode (CCM) boost converters and more particularly to continuous conduction mode (CCM) boost converters with boundary control mode. The embodiments herein achieve a scheme to achieve complete soft switching of all the switching elements of a boost converter, without incorporating any additional auxiliary switch, wherein total soft switching is achieved by inserting a fly back transformer in series with a normal boost converter operating in a continuous conduction mode, and adopting boundary control mode.
    Type: Grant
