Handheld power tool including an oscillating excitation actuator

A method for operating a handheld power tool, the method comprising:

• generating, via a controller associated with a measuring circuit, at least one control signal for the inverter from a predefined setpoint value and a measured value detected by the measuring circuit, wherein the handheld power tool includes at least one drive unit, which includes at least one oscillating excitation actuator for an oscillating drive of an associated insertion tool, an electronics unit for providing a controlled energy supply of the drive unit, the electronics unit including at least one inverter, one transformer, and the measuring circuit, the inverter being configured to generate a primary-side transformer voltage and a primary-side transformer current of the transformer, the transformer being configured to transform the primary-side transformer voltage and the primary-side transformer current into an application-specific supply voltage and a supply current for the drive unit, and the controller associated with the measuring circuit;
• and
• performing a primary-side measurement of the transformer voltage and the transformer current of the transformer, wherein the measuring circuit is situated between the inverter and the transformer.
