Inverter (logic gate) - Wikipedia

Digital electronics circuits operate at fixed voltage levels corresponding to a logical 0 or 1 (see binary). An inverter circuit serves as the basic logic gate to swap between those two voltage levels. Implementation determines the actual voltage, but common levels include (0, +5V) for TTL circuits.

Conventional air conditioners often run for decades. Our 1.5HP Samsung inverter is just shy of five years old. So far it has blown out two main circuit boards because lizards crept into the high power main circuit board in the outdoor unit. This incinerated the poor lizard and the circuit board. Each board cost P7,000 ($155) to replace.

Power inverter - Wikipedia

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 design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.
