Preventing capacitor reverse biasing during discharge in medical device

A computer-readable storage medium storing instructions thereon that when executed cause one or more processors to:

• discharge a plurality of capacitors to a discharge voltage level, wherein the instructions that cause the one or more processors to discharge the plurality of capacitors to the discharge voltage level comprise instructions that cause the one or more processors to repeatedly discharge the plurality of capacitors when coupled in series and partially recharge one or more capacitors of the plurality of capacitors when coupled in parallel until a voltage across the plurality of capacitors coupled in series is approximately equal to the discharge voltage level,
• wherein the instructions that cause the one or more processors to discharge the plurality of capacitors when coupled in series comprise instructions that cause the one or more processors to discharge the plurality of capacitors when coupled in series to respective intermediate threshold voltage levels of a plurality of intermediate threshold voltage levels, and
• wherein the instructions that cause the one or more processors to partially recharge the one or more capacitors when coupled in parallel comprise instructions that cause the one or more processors to, in response to a voltage across the plurality of capacitors coupled in series reaching the respective intermediate threshold voltage levels, charge the one or more capacitors of the plurality of capacitors to respective intermediate common voltage levels of a plurality of intermediate common voltage levels when coupled in parallel.
