BI-POLAR AND MULTI-PHASE SIGNAL GENERATOR Russian patent published in 2009 - IPC H02M7/5387 

FIELD: electricity.

SUBSTANCE: bi-polar and multi-phase signal generator may be used in defibrillators with bipolar and multi-phase shape of pulses and intense bi-polar and multi-phase electric pulses generators. The signal generator contains serial connection of induction coil and uniform cells to generate both positive polarity signal and negative polarity signal. There can be one or several cells. Each cell include electric power storage unit which is in parallel connection with two serial connected electronic bugs with the integrated by-pass diode. The electronic bugs are coupled so that they can close positive polarity generation control circuit and negative polarity generation control circuit accordingly. In addition the connection point of both bugs is the first cell terminal. In parallel to power storage unit, two serial-connected electronic bugs are connected. In parallel to the latter bugs, discrete by-pass diodes are connected. The by-pass diodes are connected so that can close negative polarity switching control circuit and positive polarity switching control circuit accordingly. In addition the point of the above bugs connection is the second cell terminal.

EFFECT: combination of signal generation circuit and positive and negative polarity switching circuits and reduction of total power storage units number.
