• Overall Machine Control Core: Acting as the "brain" of the electric pressure cooker, it is responsible for collecting sensor signals, executing user commands, and controlling all actions such as heating.
• Power board + Control board: The mainboard typically consists of two parts, the power board responsible for power supply and the control board responsible for logical decision-making.
• Three power supply solutions: The power board primarily employs three approaches—capacitive voltage reduction (low-end), linear transformers (mid-range reliability), and switching power supplies (high-end efficiency).
• Multi-level voltage output: Converts 220V AC power into +12V DC (for driving relays) and +5V DC (to power the main control chip).
• Microcontroller main control chip: The core logic device on the control board, which is internally programmed with cooking curves and control programs tailored to various ingredients.
• Relay heating control: Using the relay as a switching component, it receives chip commands to turn the power on or off for the heating element, enabling intermittent heating.
