Application of IR2130 three-phase fixed frequency output of the power supply system wiring diagram


Posted on Mar 28, 2007

Application of the above advantages make it move down 1R 2130 can be easily used for DC cut crossing speed, DC servo system, three-phase power inverter, switching power supply

and the inverter power supply, uninterruptible power supply (UPS) and AC drive system, space is limited to name three down to illustrate the application. (1) in a six-phase step wave fixed output frequency electrical power system: Figure 12-43 shows a typical three-phase fixed frequency output power schematic. in graph. Power IR2130 own work from 7805 three-terminal regulator, the input pulse from 74175N six divider, while 555 astable multivibrator is used as a fixed amount rate of occurrence device, which outputs a fixed frequency to six times the output frequency. Obviously, the figure applied shunt is taken to measure the size of the load current, and the IR 2130 fault signal output directly to drive the light emitting diode fault display. The power supply can be used for testing and can be used to the 60Hz frequency alternating current into alternating current as ordnance, aerospace systems test chamber power supply.
