Abstract

An electrical control board includes a substrate including first to fourth mounting areas, and having first and second side edges in a length direction. The first and second mounting areas are adjacent to the first side edge and arranged in sequence in a width direction. The third and fourth mounting areas are adjacent to the second side edge and arranged in sequence in the width direction. The electrical control board further includes a main control chip circuit in the first mounting area, an active PFC control circuit and a frequency conversion control circuit in the second mounting area, a power input circuit in the third mounting area, and a function interface circuit in the fourth mounting area. The power input, active PFC control, frequency conversion control, and function interface circuits are sequentially connected. The frequency conversion control and function interface circuits are connected to the main control chip circuit.
