    Abstract: Multilevel converters and space vector modulation operating methods are presented in which fewer than all possible switching states are employed for space vector modulation of rectifier and inverter circuits to promote common mode voltage contribution cancellation or reduction therebetween and by using subsets of possible space vector modulation switching states associated with minimal positive or negative common mode voltages and in some cases using virtual vectors which have zero common mode voltages to eliminate the 3rd order harmonic components in common mode voltage as well as to reduce common mode voltage affects associated with multilevel inverter stages.

    Abstract: A system comprising low cost topology for power converter systems is provided. The system takes advantage of the voltage-boost characteristic of a current source inverter (CSI) and utilizes a PWM CSI as a grid-side converter for power generation systems. Moreover, the generator-side converter employs low-cost devices, such as, but not limited to diode bridge, thyristor bridge, and/or a combination of diodes and thyristors, and accordingly simplifies generator-side converter and control. Further, the system provides a wider range of operation than traditional voltage source converter based topologies that utilize a voltage source inverter (VSI) as the grid-side convertor along with a diode rectifier as the generator-side converter.

    Abstract: A method and apparatus controls power consumption of at least one processor core by generating dynamic voltage and clock frequency scaling control information based on stochastic controller control parameters and workload performance error data. A processor core's voltage and clock frequency is varied based on the generated dynamic voltage and clock frequency scaling control information. In one example, a stochastic controller, is coupled to a dynamic voltage and clock frequency scaling (DVFS) circuit. The stochastic controller uses the stochastic controller control parameters and workload performance error data and generates the dynamic voltage and clock frequency scaling control information to control the DVFS circuit. Related methods are also disclosed.
