Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To realize a power-supply circuit which eliminates the need for a voltage limiting circuit and/or a protective circuit which are used to reduce an increase in a calorific value, when an abnormality is generated due to the short circuit or the like of a load. SOLUTION: When an abnormality is generated in a load 10 and in a power- supply circuit, a second inductor 11 is made to function. As a result, the value of the inductor 11 is made large, the peak circuit of an inductor current is reduced, and electric power which is consumed in the load 10 and in the power- supply circuit is reduced. As a result, an increase in the calorific value of the load 10 and of the power-supply circuit is suppressed, and the power-supply circuit which does not require a current limiting circuit and/or a protective circuit can be realized.
