SYNCHRONOUS HYSTERESIS MOTOR START-UP DEVICE Russian patent published in 2020 - IPC H02P1/46 H02P27/06 H02H5/04 

FIELD: gyroscopic equipment.

SUBSTANCE: synchronous hysteresis motor start-up device comprises an inverter, an output connected to the load connection terminals, consisting of transistor switches, connected by two-cycle circuit and operating in saturated mode, master oscillator, output of which through series-connected frequency switch and phase splitter is connected to control inputs of inverter, frequency selector input is connected to first timer output, which input is connected to master oscillator output, by input connected to power connection outputs. Device includes three-phase rectifier, output of which is connected to first input of inverter, and input—to terminals for connection of load. Inverter second input is connected to power connection terminals. There is a thermocompensating voltage stabilizer, the output of which is connected to supply inputs of the master oscillator, phase splitter, frequency selector and timer, second output of which is connected to inverter third input. Transistor keys of inverter are configured to switch from saturated mode to active mode.

EFFECT: technical result is high accuracy of gyroscopic angle sensor, improved weight and size parameters and thermal mode of electronic device.
