A defibrillator having a self test operation requiring reduced energy is provided. During a self test operation of the defibrillator, it is necessary to deliver a test pulse to a test load under appropriate levels of voltage and current stress to the HV circuits. In verifying the functionality of an HV switch under self test, several critical parameters must be evaluated. First, the voltage stress test is conducted at the maximum voltage level to ensure that the dielectric withstand voltage of the various components of the HV circuit are adequate under maximum voltage conditions. Second, the current stress test is conducted at the maximum current level but at a partial voltage which consumes substantially less energy. The maximum voltage and maximum current levels may be chosen to exceed the operating voltage and current levels encountered during normal operation of the defibrillator to more fully test the HV switch.
