electrical engineering project
Hi i need help with this project. My project is a solar-powered wireless charging device and my job for this project was to create a transmitter circuit for the device. I have attached a picture of the calculations and the schematic of what I did, I also added the templates for how this report is supposed to look, and I add everything that is required for this report. This is a word doc on why I have choose these parts for the transmitter. I only need a mini report for this
The report has to be in an ieee format exactly what it says in the PowerPoint I sent you
that’s all my exact requirements
Requirements:
Transmitter
timer IC 555 – The 555 timer can control the charging and discharging of a battery, which is crucial for efficient and effective charging. Its low power consumption helps prolong the battery life of the charger, which is especially important in a solar-powered application. Additionally, the 555 timer IC is easy to use, requiring minimal external components for operation. Its stable output ensures consistent charging voltage and current for the battery, which is necessary for safe and efficient charging.
general-purpose NPN transistor BC547 – It can be used for amplification, allowing for increased current and voltage from the solar panel. Additionally, it can be used as a switch to control the flow of current in the charging circuit, depending on the battery’s state of charge. This helps to ensure that the battery is charged safely and efficiently.
N-channel MOSFET IRF540N – Its low ON resistance means that it can handle high currents without generating too much heat, making it ideal for switching high-power circuits like solar panels. Additionally, it can handle high voltages of up to 100V, making it suitable for use in circuits with higher voltage requirements. Its fast-switching speed makes it appropriate for circuits that require rapid switching, such as solar-powered wireless charging devices.
5-volt series voltage regulator 7805 – This helps ensure that the charging voltage for the battery remains constant, regardless of variations in the input voltage from the solar panel. Additionally, the 7805-voltage regulator includes built-in overvoltage protection to prevent damage to the battery and other electronic components in the event of voltage spikes or surges. It also includes built-in thermal protection to prevent damage due to overheating.
Receiver
a current regulator (buck and boost) IC MC34063 – Its primary function is to regulate the voltage and current flow between the solar panel and the battery, ensuring maximum power transfer efficiency. The MC34063 is a versatile IC that can perform both buck and boost conversion, which means it can efficiently convert the input voltage from the solar panel to the required voltage for charging the battery. Additionally, the MC34063 IC includes a built-in current limiting feature that can prevent overloading and damage to the electronic components by keeping the charging current within safe limits. The IC can operate over a wide range of input voltages and output currents, making it ideal for use in a solar-powered wireless charging device.
Schottky diode (1N5819) – Is an important component in a solar-powered wireless charging device because it helps prevent reverse current flow between the battery and the solar panel. When the solar panel generates electricity, it can push current back into the battery, which can cause damage to the battery and decrease its lifespan. The Schottky diode is a special type of diode that has a low forward voltage drop and fast switching speed, making it ideal for use in a solar-powered wireless charging device. The low forward voltage drop ensures that there is minimal power loss when current flows through the diode, which helps maximize the charging efficiency of the battery. The fast-switching speed ensures that the diode can respond quickly to changes in the current flow, which helps protect the battery from damage due to voltage spikes or surges.
