Single-Phase Sine Wave Frequency Inverter Power Supply

Abstract

Single-phase sine wave frequency inverter power supply can be used to convert Direct Current (DC) into Alternating Current (AC) in order to power up some ac device when people only have dc power. Our design is to create a device that we can change its frequency and output voltage. So we use inverter circuit to produce ac current and use Microcontroller to change its frequency. Eventually this circuit can generate 40-50Hz sin waves which can be used to replace ac power in some situation.
