Single-chip inverter for active filters [PDF]
Generally inverter-based active filters, which employ pulse-width-modulated (PWM) techniques, use microprocessors for overall control and discrete logic for the generation of switching patterns.

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

Self-precharge in single-leg flying capacitor converters [PDF]
Flying Capacitor (FC) multilevel pulse width modulated (PWM) converters are an attractive choice due to the natural voltage balance property. During start-up of the converter, care has to be taken that the power switches are not exposed to voltage ...
