Abstract

main switching transistors(Q1,Q2); a main transformer(T1); a driving transformer(T2); a driving adjusting circuit(4); a regular feedback circuit having a condenser(C8) and the first. switch(SW1); a monostable multivibrator(6) for receiving a load voltage detecting signal of the first. output(P1); the second. switch(SW2) for being controlled by the monostable multivibrator; a regulator IC(8) for outputting a stable voltage from an unstable output voltage of a wiring(L5) in the regular feedback circuit; a SCR device(TH1) for triggering the switch(SW1) to stop the main switch driving circuit when excessive loads and currents are being applied to the circuit; thereby achieving a miniaturization of DC converter.
