Filed: 1994-02-21
Abstract: PURPOSE:To prevent an output overvoltage with a simple circuit, by using an overcurrent protective circuit for stopping on-off operation of a switching element when a current in the switching element is over a given level. CONSTITUTION:An overvoltage protective circuit 39 is used for stopping on-off operation of a switching element 6 when a current in the switching element 6 is over a given level. The current carried at the switching element 6 is detected by a resistor 21. A switching control circuit 11 is stopped in operation by turning on a transistor 36, and the switching element 6 is held in an off state when the sum of voltages at a diode 35 and the resistor 21 becomes over a voltage between the base and emitter of the transistor 36. In this way, the current of the switching element 6 is limited to a given level, and electromagnetic energy stored at the choke 5 is limited. Then, an electric charge stored in the capacitor 8 is also limited.
