解释“supply power not found, using dummy regulator”的含义 “supply power not found, using dummy regulator”这条信息意味着系统在尝试寻找并配置某个电源供应(supply power)时未能成功找到。因此,系统转而使用一个虚拟的或模拟的调节器(dummy regulator)来代替。这个虚拟调节器不会实际提供电力,但可能允许系统...

6.2 Using a Shunt Regulator The Zener diode provides a simple and cost effective solution. However, due to the tolerances on the Zener voltage, it might not meet the voltage regulation requirement. A more accurate shunt regulator can be used to improve the voltage regulation, as shown in ...

The reference voltage is derived from a zener diode biased by a resistor connected across +VCC and the base of the "kick'' transistor. Its emitter is regarded as output of the regulator and its collector can be tied to +VCC. When the power supply is connected to AC mains, the "kick'...
A few posts up, TimNJ had mentioned that my 30 V MOSFET was probably not the best choice for a 24 V rail due to overshoot during switching. When I put my circuit back together and connected up the LED strip, instead of my dummy power resistor load, Vds was reduced to just 10 V du...
I have received a number of calls and letters from operators and technicians that are having trouble obtaining replacement capacitors for switching regulator power supplies. I recommend using Nichicon brand capacitors. I have been using them for almost two years and to date I have not seen a repe...
