MICROPROCESSOR CONTROLLER POWER CMOS STABILIZATION PHASE mains voltage autotransformers CONTROLLED stress redistribution (ATRPN)

摘要

Microprocessor power CMOS regulator stabilize the three-phase AC voltage for autotransformers controlled stress redistribution (ATRPN) includes: a power module; control module; overcurrent fee; PSU ~ 220 / 5V 3A stabilized; input power starter. The power module includes a six transistor CMOS structure of powerful key and connected to windings ATRPN bias voltage for the power module taken from secondary windings of each phase ATRPN. The control module includes: a microprocessor; indicator; analog-to-digital converter; a relay low voltage and performs high-speed and high-precision measurement of the input and output voltages and output currents. Furthermore, the control unit performs stabilization of the output voltages by controlling the power module of the 6 channels, and the control unit carries out an emergency shutdown of the stabilizer, the low-current by incorporating a relay. To control current connected module board to which the microprocessor come magnitude of the stresses which are proportional to the output currents of each phase stabilizer. The power supply 220 VAC / 5B 3A stabilized fed from the three input phases of the stabilizer actuator prior to the input power through three diodes and provides power to the control unit. Technical result -reduction quantities switching currents, the improvement of output voltage waveform, improving the accuracy and speed of measurement values, and the performance, size reduction and weight reduction of noise introduced into the network, increasing the fire-Security, increase noise immunity, increased thermostability. 4 yl.
