ELECTRIC IMPULSE DE-ICING DEVICE Russian patent published in 2014 - IPC B64D15/12 H05B3/84 

FIELD: electricity.

SUBSTANCE: electric impulse de-icing device may be used for ice removal from metal sheet surfaces, for example, from wings covering of air planes. The claimed device comprises a number of inductors placed closed to de-iced metal surface. The inductors are coupled to outputs of the respective modules, which inputs are connected through a circuit breaker to the supply mains. Each of the modules comprises a charger, a storage capacitor, a monitoring key, a protective diode and control pulse generator. The charger input is coupled to the module output while its output is coupled to the storage capacitor. Output of the storage capacitor through the monitoring key is coupled to the module output. The protective diode is connected in parallel to the module. Besides, the claimed device is equipped with an adjustable control pulse delay unit and low-energy supply unit. The module input is coupled to the supply unit input while feeding inputs of the generator and adjustable control pulse delay unit are coupled to the module output. The generator and adjustable control pulse delay unit are coupled in series. Input of the monitoring key is coupled to output of adjustable control pulse delay unit.

EFFECT: device allows even distribution of the modules operation in time, reduction of load to the supply mains.
