3 EEL6246 Pwer Electrnics II Chapter 6 Lecture 6 Dr. Sam Abdel-Rahman Mde I [ 0 t < t ]: Assume fr t < 0, the switch is clsed while D is pen. At t0, the switch is turned OFF, allwing the capacitr t charge by the cnstant current I in, I in il ic dv C dt With the initial capacitr vltage equals zer c Iin v t C t c ( ) The capacitr vltage reaches the utput vltage at t t v ( t ) V, t CV I in At t t v V,the dide starts cnducting since, and the cnverter enters Mde II. c Steady-State Analysis c (6.76) (6.77) (6.78) 3

5 EEL6246 Pwer Electrnics II Chapter 6 Lecture 6 Dr. Sam Abdel-Rahman Mde III [t 2 t < t 3 ]: Mde III starts at t 2 when v c reaches zer, and the switch dide (anti-parallel dide) turns ON, clamping the vltage acrss C t zer At t t 2 ', S turns ON at ZVS. The switch picks up the current, and the inductr current linearly increases t I in. The initial cnditins at t t are, vc ( t ) il ( t2) Iin csω ( t2 t) Bk Crrectin (6.82b) Because the capacitr vltage is zer, the inductr vltage is equal t the utput vltage. di L L dt V The inductr current becmes, V il ( t) ( t t 2 ) + il ( t2 ) (6.84) L T achieve ZVS, the switch can be turned ON anytime after t 2 and befre t 2. At t t, i reaches I in (Bk Crrectin), resulting in the time interval given in Eq. (6.85) 3 L L ( t3 t2) in L t2 V [ I i ( )] Steady-State Analysis (cnt d) (6.82a) (6.83) (6.85) 5

Mde IV [t 3 t < t 4 ]: Steady-State Analysis (cnt d) At time t 3, the inductr current reaches I in (Bk Crrectin), and the utput dide turns OFF, but the switch remains clsed.
