The core of EMC in ESWL is "shutting down" the high-voltage pulse. For electrohydraulic systems, the discharge electrodes and their high-voltage cables should be surrounded by a full metal shield, which should be reliably grounded. The connection between the energy storage capacitor bank in the discharge circuit and the electrode should be as short and thick as possible. In the circuit controlling the trigger switch (e.g., the gap), a light-controlled high-voltage switch or strict opto-isolation should be used. For electromagnetic systems, the current loop area of the drive coil should be minimized, and a metal shield may be used. The power and signal lines of auxiliary equipment such as the X-ray generator or ultrasound probe should be independently filtered and shielded, and separated from the power supply of the main shock wave generator.
