Electromagnetic-based ultrasonic residual stress relieving system

An electromagnetic-based ultrasonic residual stress relief system, comprising:

• a capacitor charging module;
• a high-pulsed current capacitor that is charged by the capacitor charging module;
• a latching switch for high voltage charging that controls current from the from the capacitor charging module to the high voltage capacitor;
• a spark-gap trigger module;
• a spark-gap trigger circuit;
• a non-latching switch for spark-gap trigger that controls current from the spark-gap trigger module to the spark-gap trigger circuit;
• and
• a planar coil,
• wherein the high-pulsed current capacitor is charged by the capacitor charging module under control of the latching switch, and
• wherein the non-latching switch for spark-gap trigger discharges energy from the high-pulsed current capacitor into the spark-gap circuit, which discharges energy into the coil.
