FAQs about Inverter voltage type conversion current type
What is the difference between a converter and an inverter?
A converter changes the voltage level of electricity while maintaining the same type (AC to AC or DC to DC), whereas an inverter converts electricity from DC to AC. A converter is a device that changes the voltage of an electrical power source, either stepping it up or down, but it doesn't alter the current type (AC to AC or DC to DC).
