Abstract

PURPOSE: To stabilize the magnetic flux density of an output converting transformer by increasing output constant voltage precision by adding a circuit which controls the conduction period of a main transistor according to an input voltage.
CONSTITUTION: Control circuit B is that which maintains the DC output of output circuit A at a constant voltage. The circuit B is equipped with voltage time product detecting circuit Tc1 which sets the nonconduction period of main transistor Q according to its output voltage, voltage time product detecting circuit Tc2 which sets the conduction period of main transistor Q according to the input voltage, and flip-flop FF which synchronizes both detecting circuits Tc1 and Tc2 with each other.
