Abstract

Power tools and methods for motor control. One embodiment provides a power tool including a motor (400), an inverter bridge (228) electrically connected between the power input (340) and the motor (400) including a plurality of switches including wide bandgap transistors. The power tool further includes a controller configured to drive the motor using the power switching network, a pulse width modulation (PWM) generator (276) configured to generate an interrupt at a predefined interval, and a current detector (236) configured to sample a phase current of the motor in response to the interrupt.
