In this paper, a new family of single-stage high step-up boost voltage inverter based on transformer is proposed, called T-Z source inverters. By replacing two inductors in the classical Z-source inverter with two transformer, the proposed inverter produces a very high boost voltage gain when, the turn ratio of the transformer is larger than one. Compared to the trans-Z source inverter, the pro...

The multilevel inverters have highly desirable characteristics in high power high voltage applications. The multilevel inverter was started first with diode clamped multilevel inverter. Later, various configurations have been came into existence for many applications. However the multilevel inverters have some demerits such as requiring higher number of components, PWM control method is complex...

 The advent of the transformerless multilevel inverter topology has brought forth various pulse width modulation (PWM) schemes as a means to control the switching of the active devices in each of the multiple voltage levels in the inverter. An analysis of how existing multilevel carrier-based PWM affects switch utilization for the different levels of a diode-clamped inverter is conducted. Two ...

Low-power dichroic halogen lamps, usually used for display lighting, have low-voltage filament. The lightweight electronic transformer (ET), based on self-oscillating half-bridge high frequency inverter, are used to replace bulky and heavy conventional 50160 Hz step-down transformer. But their lamp current are rectangular like shape, leading to generate high electromagnetic noise and increase t...
