330uf/16v ELECTROLYTIC CAPACITOR

This capacitor is a crucial low-voltage component used in the control and auxiliary power supply circuits, which are essential for the overall system compliance and protection logic.

Here are its core specifications and relevance to the inverter:

• Type: Electrolytic (Aluminum) or Multilayer Ceramic (MLCC), depending on required size and frequency response. Electrolytic is common for high capacitance values like this.

• Capacitance: 330uF (Microfarads).

• Voltage Rating (V_DC): 16V (Maximum working voltage).

• Tolerance: Typically, 20% for electrolytic types.

• Function in Inverter/Compliance: This capacitor would be used on the low-voltage side of the control board (e.g., 12V or 15V auxiliary supplies) for:

  • Filtering and Decoupling: Providing essential filtering and ripple reduction on the DC supply rails for sensitive chips like the IR2112, TL084CN, and the digital logic (74LS/CD4000 series). Clean power rails are fundamental to reliable operation and meeting general safety Standards.

  • Timing: Used in conjunction with ICs like the NE555 or the CD4518BE to define time constants for soft-start or controlled shutdown sequences, which are part of the overall 120C thermal Protection scheme.
