An EMC circuit is a circuit specifically designed to ensure that electronic equipment meets electromagnetic compatibility (EMC) requirements. Its core objective is to ensure that the device can operate normally in the same electromagnetic environment without being affected by interference from other devices, and without causing harmful interference to other devices. Such circuits typically include protection components and filtering structures to cope with common electromagnetic interference sources. The LDO circuit connected to the 5V power supply circuit is a voltage regulator circuit using linear adjustment elements; it is simply applied and therefore not described in detail.

Furthermore, the power supply circuit includes an EMC circuit and a PFC boost circuit connected to the EMC circuit, which can improve electromagnetic interference resistance and ensure the normal use of subsequent circuits, thus improving reliability. In addition, it can meet the usage requirements of different situations when used with the auxiliary light circuit, thereby expanding its applicability.
