Source: InternetPublisher:风向西瓜 Keywords: Application specific integrated circuits lanterns rectification filtering Updated: 2021/03/06
The holiday lantern controller circuit made with SH-9043 is shown in Figure 2-84. After the 220V AC power is bridge
-rectified by VDl~VD4 , it outputs full-wave pulsating DC power to power the lanterns H1~H4. The other ~ path supplies power to the integrated block A through Rl current limiting and CI filtering
. Adjusting RP can change the vault chasing speed of the four-way lanterns HI~H4.
