Electrical control board, air conditioner outdoor unit, and air conditioner

An air conditioner outdoor unit comprising:

• an electrical control board including:
• a substrate including a first mounting area, a second mounting area, a third mounting area and a fourth mounting area, the substrate having a first side edge and a second side edge in a length direction, the first mounting area and the second mounting area being positioned adjacent to the first side edge and arranged in sequence at the substrate in a width direction, and the third mounting area and the fourth mounting area being positioned adjacent to the second side edge and arranged in sequence at the substrate in the width direction;
• a main control chip circuit arranged in the first mounting area;
• an active power factor correction (PFC) control circuit and a frequency conversion control circuit both arranged in the second mounting area;
• a power input circuit arranged in the third mounting area;
• and
• a function interface circuit arranged in the fourth mounting area;
• wherein the power input circuit, the active PFC control circuit, the frequency conversion control circuit and the function interface circuit are sequentially connected, and the frequency conversion control circuit and the function interface circuit are connected to the main control chip circuit.
