  • Description
  • During the saturated conduction of switch tube VT, the DC voltage Ui of C1 positive pole is charged through L → VT → C2 positive pole → C2 negative pole. On the one hand, the DC voltage is established at both ends of C2, and on the other hand, the magnetic energy in the energy storage inductor L is continuously increased. When the switch tube VT is cut off, L induces left negative and right positive voltage, and the magnetic energy in L is released to C2 and load through the freewheeling diode VD. The voltage Uo at the output end of the power adapter is determined by the saturation on-time of the VT, that is, the base excitation pulse width. The width of the base excitation pulse is determined by the error sampling and amplification circuit.
