Inverter circuit of portable energy storage power supply

What is a portable AC & DC power supply?

The aim of this project is to build a portable AC and DC power supply using solar panel to harness solar energy since it is considered a form of renewable energy which is readily available. The power supply will be used for powering up some low power home appliances. As it is portable, it could also be used for outdoor activities. II.

What is the system architecture of portable solar power supply?

A. System Architecture The system architecture of the portable solar power supply is illustrated in Fig. 3. The prototype consists of : Solar panel for charging up the battery bank. Charge controller to prevent over-charging which is detrimental to the health of the battery. Voltage regulator for regulating a constant 5V DC power supply.

What is a portable solar power supply?

VI. CONCLUSION A portable solar power supply was successfully built to the specification. The product is able to support simultaneous operation of low-power rated electrical appliances and charging of mobile phones. The product makes use of a 17V solar panel to capture the sunlight and convert it to electrical energy.

How does a portable solar power supply work?

Abstract—This paper presents the building process of a small scale, cost effective portable solar power supply. The end product comes with a solar panel to capture and convert solar energy to electrical energy. The electrical energy was stored in rechargeable battery with a charge controller to regulate the charging process.

What is a square wave inverter?

A low-cost square wave inverter was built to generate the AC power supply required for the operation of low power rated household devices. A voltage regulator was constructed to step down the 12V DC voltage to a regulated 5V DC power supply for the charging of handheld devices like smartphones and tablets.

Can a rechargeable battery be used as an inverter?

The flow of electrons through the external circuit constitutes the direct current which could be stored in a rechargeable battery. An inverter could then be used to convert the direct current (DC) to alternate current (AC) to power up electrical appliances that rely on AC power supply.
