Circuit Arrangement and Method for Controlling an Electrical Consumer
Abstract:
The invention relates to a circuit arrangement for controlling an electrical consumer (M), said arrangement being provided with a bridge circuit which comprises four electronic switches (V1, V2, V3, V4) and the consumer (M) which is arranged in the transversal leg of the bridge circuit, and a control circuit (uC) comprising control terminals for the four electronic switches. The control terminal for the first electronic switch (V1) is connected to the control terminal for the fourth electronic switch (V4) by means of a series connection consisting of a first capacitor (C1) and a first resistance (R1), and the control terminal for the third electronic switch (V3) is connected to the control terminal for the second electronic switch (V2) by means of a series connection consisting of a second capacitor (C2) and a second resistance (R2). The invention also relates to a method for switching an electronic switch by means of a control circuit (uC) comprising a control terminal for controlling the electronic switch which can either be switched (“tristate”) as an input (“high impedance”) or as an output (“low” or “high”). The switching of the electronic switch from the conductive slate to the non-conductive state and/or vice versa is carried out in two steps, namely the control terminal is switched from “low” via “high impedance” to “high” or from “high” via “high impedance” to “low”.
