Title: DC/DC inverter using PZT
Inventor: LEE JONG HWA
IPC: H02M7/537
Filed: 2001-12-26
Abstract: PURPOSE: A DC/DC inverter is provided to make a driver circuit shut down when a load is opened by sensing an open load state of a cathode ray tube simply. CONSTITUTION: A comparison part(3) compares an input voltage with a reference voltage, and a voltage regulating oscillating part(4) controls a pulse width according to an input of an output signal of the comparison part. A driving part(1) converts into an AC component a voltage of an input DC component switched and received by an output of the voltage regulating oscillating part. A piezoelectric transformer receives a variation amount of an output voltage of the driving part and transforms the output voltage into a constant voltage according to an adjustment gain which is set corresponding to the variation amount. A cathode ray tube(CCFL) is connected to output terminals of the piezoelectric transformer and performs a luminescence operation according to an output voltage of the piezoelectric transformer. A rectification part(2a) rectifies a DC voltage conducted to a ground side through the cathode ray tube to supply the rectified voltage to the comparison part, and outputs a signal inversely proportional to a magnitude of the rectified voltage signal through an A output terminal. Resistors(R2,R3) divides a voltage output through the A output terminal of the rectification part when a voltage conducted to the ground side through the cathode ray tube, and a transistor(Q1) has a base connected to receive the divided voltage. The transistor is turned on when a voltage over a limited voltage is applied, so that charges are charged in a condenser(C1).

Title: Control method for electically driving actuator for inlet guide vane
Inventor: KIM BONG JAE
IPC: F04D27/00
Filed: 2001-12-29
Abstract: PURPOSE: An actuator controlling method is provided to simplify power transmission and a structure of an actuator by linearly controlling the actuator. CONSTITUTION: Firstly, it is determined whether or not a valve is automatically operated(12). If the valve is automatically operated, Ampere of an electric motor is inspected(16). Then, an opening degree of an inlet guide vane is determined(17). After that, present pressure is compared with predetermined pressure(18). If present pressure is lower than predetermined pressure, it is determined whether or not an error value is larger than a dead band range and the actuator is in a maximum Ampere state(20). Then, it is determined whether or not a proportional variation of the inlet guide vane is larger than 3(21). An increased value of the inlet guide vane is achieved by adding a differential variation of the inlet guide vane(22). Then, the actuator is operated so as to increase an opening degree of the inlet guide vane(24). After determining whether or not the actuator is a minimum Ampere(27), it is determined whether or not a proportional variation of the inlet guide vane is larger than 3(28). If the proportional variation of the inlet guide vane is not larger than 3, the proportional variation is changed into a negative value through multiplying the proportional variation by -1. After obtaining increased value of the inlet guide(31), an actuator is operated in such a manner that the opening degree of the inlet guide vane is reduced(33).
