  1. Steady state solution of state planeTwo possible trajectories for given M and J

  2. Two possible trajectories for given M and J

  3. Two possible trajectories for given M and J

  4. Steady state solution of state planeSolve for initial conditions Mc0 and JL0

  5. CCM output plane characteristics

  6. Why all diodes become forward-biasedCapacitor current waveform explanation CCM near DCVM boundary

  7. State plane trajectory: DCVM As predicted by CCM analysis DCVM trajectory DCVM occurs when

  8. Discontinuous conduction mode(DCVM) • Occurs at heavy load and low output voltage • During the “discontinuous” interval, all four output diodes are forward-biased • The capacitor voltage waveform exhibits an additional subinterval with vc = 0

  9. DCVM solution Mode boundary Steady-state solution • Output characteristics • Solid lines: CCM • Dashed lines: DCVM
