3KW 24V | JLCPCB
The video demonstrates building a 3KW inverter with a peak power of 4KW, featuring a custom PCB design, enhanced MOSFET driving with a totem pole driver, and comprehensive protection mechanisms including overcurrent protection.
MAIN POINTS FROM TRANSCRIPT
- The inverter is designed for 3KW with a peak power of 4KW and operates at 24V.
- A custom PCB is used, with quality PCBs available from JLCPCB.
- A totem pole driver is added to enhance MOSFET driving capabilities.
- Protection features include a shunt resistor for overcurrent measurement.
TAKEAWAYS
- Use 63V-2200uF capacitors for safety, despite the inverter operating at 24V.
- Diodes are crucial for quick discharge of MOSFET parasitic capacitance.
- The shunt resistor, made of copper bars, measures current to prevent overcurrent.
- Files for the inverter design are available for download in the video comments.
