"What device convert DC to AC?
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). The input voltage, output voltage and frequency, and overall power handling depend on the…"
"Converting DC power from one voltage to another is much more complicated. One method of DC-to-DC conversion first converts power to AC (using a device called an inverter), then uses a transformer to change the voltage, and finally rectifies power…"
"Applications of AC Current
Home and office outlets are almost always used in AC. This is because generating and transporting AC across long distances and relatively easy. At high voltages like as over 110kV, less energy is lost in electrical power…"
