Abstract
An electromagnetic acoustic transducer (EMAT) system for inspecting a part includes an EMAT sensor and a power supply for supplying an output power to the EMAT sensor. The power supply includes a DC/DC converter to boost an input DC voltage into a boosted DC voltage, a DC/AC inverter having Silicon Carbide (SiC) Mosfet power switches to invert the boosted DC voltage into an AC square voltage, and an output filter to filter the AC square voltage into an AC sinusoidal voltage. The AC sinusoidal voltage is the output power from the power supply to the EMAT sensor.
