Abstract
Embodiments described herein relate to signal generators, systems including signal generators, and related methods. A signal generator includes capacitor(s) to store energy used to generate a treatment signal. The signal generator also includes a waveform shaping circuit, a controller, a voltage sense circuit, and a current sense circuit. The waveform shaping circuit is coupled to the capacitor(s) and includes first, second, third, and fourth switches, each of which is configured to be selectively turned ON and OFF, to allow current to pass through the switch when turned ON, and to prevent current from passing through the switch when turned OFF. The controller selectively controls the switches in order to generate the treatment signal. The controller also selectively controls the switches in order to perform certain fault tests, which rely on voltages sensed by the voltage sense circuit and currents sensed by the current sense circuit.
