1. An air conditioner electric control assembly comprising:
an electric control board including:
a first alternating-current power supply input interface configured to receive an external alternating-current power supply;
a first power supply interface connected to the first alternating-current power supply input interface and configured to output a high-voltage alternating current;
a second power supply interface configured to connect a low-voltage alternating-current power supply or a low-voltage direct-current power supply;
a rectifier circuit mounting site connected to the second power supply interface;
a filter circuit mounting site connected to the rectifier circuit mounting site;
a drive circuit connected to the filter circuit mounting site;
a switch device connected to the drive circuit; and
a microcontroller unit (MCU) connected to the drive circuit and configured to control the drive circuit to drive the switch device to switch state to drive a load to operate, and
a linear transformer including a second alternating-current power supply input interface connected to the first power supply interface and a low-voltage alternating-current power supply output interface connected to the second power supply interface.
