Power inverter - Wikipedia power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of "converters" which were originally large electromechanical devices converting AC to DC.Get Price
Distribution transformer - Wikipedia distribution transformer or service transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated ...Get Price
Electrical Power Transformer: Definition & Types of ...· Power Transformer Definition. A power transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer.Since, there is no rotating or moving part, so a transformer is a static device. Transformer operates on an ac supply.Get Price
