This research proposes two enhanced single-stage quasi-Z-source AC-AC converters. Both topologies have non-inverted output that utilizes pulse width modulation (PWM ...

Multilevel Inverter has been introduced since 1975 as it is alternative in high power and medium voltage situations. Multilevel inverter is like an inverter and it is used for industrial applications ...

Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly ...

Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and ...

Porsche Engineering has developed the concept of an ‘AC battery’ for electric vehicles that unites numerous components in a single part. It is controlled by a standardized control unit concept with a ...

When we speak of efficiency, we are referring mainly to electrical efficiency. This usage, however, is a restriction of the meaning of the word efficiency itself. In power-electronics applications the ...
