Patent JP-H11178203-A (JP)
Title: Power supply and its control method
Inventor: ISHIKAWA JUNJI
IPC: H02H7/20
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To prevent the run away of a high-voltage power supply (circuit), even if the input line of control signals is disconnected or short-circuited in the power supply in which an output voltage is converted in accordance with the values of inputted control signals. SOLUTION: A line voltage Vp of a power supply is fed to the primary side of a transformer T1, which is switched on or off by an FETQ4 to generate high voltage at its secondary side. In this process, a detected voltage Vo of the output is inputted into an operational amplifier Q3 for the feedback control, so that an output voltage Vout becomes equal to a reference voltage Vr. Also, by keeping the input line of the control signals Sc connected to the groundline via a resistor Rc of high resistance value, the control signals Sc is reduced to the ground level so as to stop the power supply (circuit), if the input line is opened or short-circuited.
