| Abstract: | In order to decrease the tipple coefficient of switching power supply, the isolated CUK type switching power supply was researched. Based on the switch mode of power supply, the constraint equations between the ripple current of power and magnetic components were deduced. With the equations, the conditions of zero tipple current input and zero tipple current output were discussed. Moreover, the magnetic integration realization method of CUK type power supply was analyzed. Simulation results validated the conclusions. |
