Summary of PURE SINE WAVE INVERTER WITH LED AND LCD
The article describes the assembly and features of a pure sine wave inverter PCB controlled by a Microchip PIC16F72A or PIC16F876A MCU. It includes protection features such as low-battery shutdown, overload shutdown, output short circuit shutdown, and high temperature shutdown. Monitoring is done via a 16x2 LCD, LED indicators, an error LED, and a buzzer. The power supply voltage ranges from 12V to 48V, with a mandatory 12V relay. The article outlines steps for PCB design, component placement, H-bridge design, testing, and finishing.
Parts used in the Pure Sine Wave Inverter Project:
- Microchip PIC16F72A or PIC16F876A MCU
- 12V relay
- 16x2 LCD display
- LED indicators
- Error LED
- Buzzer
- 300W transformer
- Various PCB components (resistors, capacitors, transistors, etc.) as per PCB design
- H-bridge board components
The inverter PCB is easy to assemble by following the label of the components to be inserted. The choice of the voltage to be used to power the inverter ranging from 12v to 48v depends on kva you are designing. for any setup, a 12v relay is to be use.
