An AC to DC converter, or rectifier, changes alternating current (AC) from the power grid into direct current (DC) used by most electronic devices like phones, laptops, and LEDs.

The DC to AC power inverter works using P-N junction diodes, which allow current to flow in only one direction. This rectification process converts AC into pulsating DC. The AC to DC transformer includes components like transformers, diodes, and filters help step down the voltage and smooth the output for stable DC power.

Why use AC to DC converter​? Because devices need steady DC power, while the grid supplies AC. That’s why DC to AC Inverter are built into chargers, adapters, and power supplies.

Homes use AC power, but when powering electronics or using solar panels, DC is essential.
