Abstract
Example systems, apparatuses, methods, and computer program products are disclosed for electroporating cells in a tissue using a set of voltage pulses generated by capacitor charge circuitry based on a voltage supply. An example method includes continuously monitoring a set of characteristics of the voltage supply and the set of voltage pulses; generating a first set of monitor signals based on the set of characteristics; detecting a first fault condition based on the first set of monitor signals; and generating a first crowbar trigger activation signal. The example computer method further includes: detecting a second fault condition based on a second set of monitor signals generated based on the first set of monitor signals; and generating a second crowbar trigger activation signal. Subsequently, the example computer method includes electrically disconnecting the capacitor charge circuitry from electroporation electrode circuitry based on either the first or second crowbar trigger activation signal.
