Multi-level topology of high power voltage source inverter for variable speed drive of electrical machines

Description

High power pumps or fans are generally driven by constant speed machines using valves. Though driving the machine at variable speed with voltage source inverters offers better energy efficiency. In the medium voltage range, the challenge is to develop efficient drives with conventional semiconductors.
Our solution: high power and medium voltage source inverter topology.
