Abstract

PURPOSE: To make it possible to improve the efficiency and also elevate the transient responsiveness, by connecting the output terminal of each constant-voltage electric power source directly and in parallel, and supplying the constant-voltage to the load, in the constant-voltage electric power source of the ringing choke converter system.
CONSTITUTION: Now, in case when the output voltage has abnormally risen due to abnormality of the electric power source panel PU2, its abnormality is detected by the voltage abnormality detection circuit ALM of the electric power source panel PU2, but the voltage abnormality detection circuit ALM of the electric power source panel PU1 outputs no alarm as long as the voltage of the tertiary winding N3 of the transformer T is kept constant by the constant-voltage control, the constant- voltage is continued, and therefore the transient responsiveness becomes excellent. Also, in case when an output of the electric power source panel PU2 has abnormally dropped, the rectifier diode of the electric power source panel PU2 becomes a reverse bias state and cuts it off, and therefore the constant-voltage can be continuously to the load from the normal electric power source panel PU1.
