This paper proposes a simple compensation method for switches of the unclamped voltage in the three-level NPC inverter. Voltages of
inner-switches can be unclamped in the three-level NPC (neutral point clamped) inverter. It can cause the problem of the switch fault
accident. By adding a capacitor, switches of the unclamped voltage can be clamped. Through the analysis of the circuit, the reason
behind switches being unclamped was verified which leads to the solution method that designs a compensation capacitor. The proposed
method was validated through the simulation and experimental results.
