POWER SOURCE FOR STATIONS OF SHIP DEPERMING Russian patent published in 2018 - IPC B63G9/06 H01F13/00 H03K3/57 

FIELD: shipbuilding; electrical equipment.

SUBSTANCE: invention relates to the field of ship deperming. Power source for stations of ship deperming contains an uncontrolled three-phase AC power source, a charger, a capacitive energy storage device, a voltage sensor, a bridge switch, current sensor, demagnetizing coil, pulse train generation device and pulse sequence parameter setting device. Output of the device for specifying the parameters of the pulse sequence is connected to the pulse sequence generation device, the outputs of which are connected to the input of the bridge switch control device and to the controlling input of the charger. Power output of the charger is connected to a capacitive energy storage device, the output of which is connected to a voltage sensor and a bridge switch. In the diagonal of the bridge switch, the demagnetize winding is connected through the current sensor and the additionally inserted low-pass filter.

EFFECT: technical result consists in improving the accuracy of forming an alternating sequence of trapezoidal current pulses in working windings by power sources of stations of unmotorized demagnetization of ships.
