FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering, laser equipment and remote power supply. Device for generation and wireless transmission of multi-phase system of voltages by means of lasers includes: control unit; units for generation and injection of power pulses and pulse pulses of laser light flux for phases A, B, C; medium for wireless transmission of power and information laser radiation; receiver of pulses of power light flux of laser frequency; receiver of pulses of laser light information flux for phases A, B, C; circuit of generation of periodic electric output signal of industrial frequency for phases A, B, C, which may contain sections with positive and negative values. Output signal of the device is formed from a sequence of electric pulses of the same duration. Electric pulses are obtained by converting the light flux received by the laser radiation receiver into electrical pulses. Luminous flux is transmitted via wireless transmission medium. Intensity of the flow is controlled by switching on a different number of emitting lasers in the laser grid. Using the control circuit, the flow intensity is controlled and a periodic sequence of rectangular pulses is generated. Each pulse of the control unit controls connection of its pumping current generation circuit and its number of lasers in the laser grid. Period of the output signal is set by the period of control pulses generated by the control unit. Amplitudes of pulses are determined by the number of lasers in the injector. Control unit generates a sequence of rectangular pulses following one another. Each pulse controls opening of power semiconductor switch, by means of which pumping current is supplied to its laser grid. Number of lasers in the grids is determined by the signal shape at the output of the device. Duration of the open state of the key and duration of radiation of the light flux emitted by the laser grid is equal to the duration of the rectangular pulse generated by the control unit. Control unit monitors the power unit pulse numbers, which have negative polarity. Pulse of the control unit opens the controlled semiconductor switch which controls supply of power to the information laser. Information laser emits a light flux pulse which is received by the information signal receiver. Power pulse received by the laser radiation receiver arrives at the output poles either directly or inverted. Signal from the output of the information signal receiver closes the direct path of transmission of the power pulse from the receiver to the output terminals and opens an inverted path for transmission of the inverted pulse. Direct and inverse paths are controlled by two controlled electronic or electromechanical keys. Periodic sequence of pulses is generated at output poles of the device and comprises pulses of required amplitude and polarity.
EFFECT: disclosed is a device for generation and wireless transmission of a multi-phase system of voltages by means of lasers.
