Title: Switching regulator
Inventor: HATAKE SHIGEO
IPC: H02H9/02
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To provide a switching regulator capable of performing overcorrect protection by a specified load current at all times regardless of change of an AC input voltage. SOLUTION: If the voltage of an AC input section 1 becomes larger, even if value of a load current is the same, the peak value of the current of a switching device 19 becomes larger. Thus control is so performed that the drive frequency of the switching device 19 is made higher by a power controlling IC 5, larger the voltage of the AC input section 1 becomes, to cause the peak value of the current of the switching device 19 not to change, even if the voltage of the AC input section 1 becomes large. Consequently, it is possible to detect a specified overcorrect of a load at all times by a current transformer 11, regardless of the change of an AC input voltage.
