Abstract
The invention relates to a contactless power-isolated supply circuit of an electronic horn and an isolation power supply method thereof. When the electronic horn is in operation, as the on-off of an electromagnetic coil can generates relatively big wave interference on a power line, the existence of such interference can influence the operation of the horn, reduce the reliability of the operation of the horn, and even cause the horn unable to normally operate when the interference is severe. In structure, the contactless power-isolated supply circuit of the electronic horn comprises: a master control circuit (1), wherein one end of the master control circuit (1) is connected with a heavy-load loop (2), and the other end of the master control circuit (1) is connected with a light-load loop (3); the heavy-load loop (2) and the light-load loop (3) are both connected with an automobile power supply; the heavy-load loop is isolated from the light-load loop through a high-power diode D2; and the light-load loop is isolated from the heavy-load loop through a low-power diode D1. The contactless power-isolated supply circuit provided by the invention can be used in automobile horns.
