SWITCHING CIRCUIT AND METHOD TO CONTROL POWER CONSUMER Russian patent published in 2011 - IPC H02P7/285 H02P25/02 H02M7/5387 H02K33/02 H03K17/16 A46B13/00 B26B19/28 

FIELD: electricity.

SUBSTANCE: switching circuit comprises four electronic switches (V1, V2, V3, V4), and its diagonal includes a consumer (M) with a control circuit (uC) with controlling outputs of four electronic switches. The control output of the first electronic switch (VI) via serially connected the first capacitor (O) and the first resistor (R1) is connected to the control output of the fourth electronic switch (V4). The control output of the third electronic switch (V3) via serially connected the second capacitor (C2) and the second resistor (R2) is connected to the control output of the control electrode of the second electronic switch (V2). In method to switch an electronic switch the control output of the control circuit to control an electronic switch may be connected as an input ("high-resistance"), or as an output ("low level of a signal") or ("high level of a signal"). The electronic switch is switched from a conducting condition into a non-conducting condition and/or vice versa is carried out in two steps: the control output switches from the "low level of a signal" via the "high resistance" to the "high resistance" to the "high level of a signal" or from the "high level of a signal" via the "high-resistance" to the "low level of a signal".

EFFECT: invention provides control over a power consumer designed for operation from a source of supply with high stray inductance.
