DC-DC CONVERTER HAVING LOW RIPPLE AND MULTIPLE HIGH VOLTAGE OUTPUT

摘要

The present invention relates to a DC-DC converter of the EPC, which is a driving power supply device for traveling waveguide amplifiers used in communication equipment for satellite and ground stations. In particular, the present invention relates to an integrated signal for applying an input current as an appropriate signal in a tube. With integrator; A chopper unit for converting a signal output from the integrator into a DC signal; A chopper control unit which generates a clock for driving the chopper unit and outputs a signal in synchronization with a switching unit; A switching unit adjusting a timing to apply a current applied through the chopper unit to a rectifying unit on a secondary side; A signal generator for controlling on / off of the switching unit and applying a synchronization signal to a chopper control unit; A maximum current detector for dropping the value higher than the average value in order to prevent a problem occurring in the system when the current output from the switching unit is higher than the average current in the tube; A comparator for comparing the current output from the maximum current detector with a reference value and comparing the value output through the amplifier with the voltage output from the rectifier with the reference value and outputting an appropriate value through the OR gate ; A low ripple and various high voltage output DC-DC converters comprising a rectifying unit rectifying a signal according to the current applied through the primary coil of the switching unit and outputting it to the load, eliminating discharge generated in the tube. This can improve the reliability of the system.
