Diode Clamped Multilevel Inverter Switching Topology
This paper presents a switch three level and five level diode clamped multilevel inverter topology which can be
used for low-medium power drive applications. The high frequency switching in conventional adjustable speed drives gives
rise to motor bearing failure & causes de rating of the switching devices & generates large switching losses. The multi-level
inverter topology is very promising in ac drives, when both reduced harmonic contents & high power are required. This
project presents the principle of diode-clamp inverter, used to control voltages per frequency, widely used because of it high
efficiency to control the speed of single-phase induction motor.
