The main advantage of asymmetrical multilevel inverters is the optimization of levels with a minimum number of power supplies. However, this optimized multilevel system still needs a large number of isolated and floating DC supplies, which makes these converters complicated to implement in electric vehicles (EVs), because the system will require many independent battery packs. In this paper, a very...

This paper deals with the control of the output part of a power electronics converter, which we have designed for a diesel-electric power supply unit for military applications. The output part of the unit is composed of a four-leg three-phase voltage source inverter and a sinusoidal filter. The output part of the power supply unit with help of proposed control system allows to create three-phase symmetrical...
A high bandwidth critical path monitor (1 sample/ cycle at 4-5 GHz) capable of providing real-time timing margin information to a variable voltage/frequency scaling control loop is described. The critical path monitor tracks the critical path delay to within 1 FO2 inverter delay with a standard deviation less than 3 FO2 delays over process, voltage, temperature, and workload. The CPM is sensitive...
