METHOD FOR ACTUATING AN INVERTER OF AN ELECTRIC TOOL AND ELECTRIC TOOL

摘要

The invention relates to power electronics and to a method for actuating an inverter for outputting an AC voltage to an ultrasound device, wherein, depending on the current and/or the voltage, an actual variable is determined, wherein the actual variable is compared with a setpoint variable and a controlled variable is determined for actuating the inverter, wherein, depending on the controlled variable, a control signal for actuating the inverter is generated in such a way that the inverter emits at least two voltage pulses during a half-cycle of the AC voltage to be generated.
