An inverter converts the DC voltage to an AC voltage. In most cases, the input DC voltage is usually lower while the output AC is equal to the input DC. This is common in battery chargers and solar panels. Inverters are often used to convert low voltages to higher voltages and can be used for other purposes such as converting alternating current voltage levels from low to high or converting an alternating current voltage level from high to low.
The following are some popular inverters:
- Amplifier: They are necessary if you require a higher power level. So say you want a 144 watt speaker, instead of purchasing four 12 watt speakers, you can purchase one 144 watt amplifier instead that will power all four speakers without any issues.
