What is the switching frequency of a power supply?

The switching frequency refers to the rate at which the DC voltage is turned on and off during the pulse width modulation process in the 277vac class 2 power supply. The switching frequency in the inverter is the rate at which the switching device turns on and off. The typical frequency ranges from a few KHz to a few MHz. The increased switching frequency not only reduces the space requirements of...

Should we need dimmable or non dimmable LED power supply?

LED power supply is the one of the most important parts for LED lighting project. Most households use 120-277V AC electricity, but LEDs operate on low voltage DC electricity, 12v, 24v, 36v, 48v. Therefore, the external power supply can changes the higher voltage AC current into the lower voltage DC current to match what the LED lights need to operate. Sometimes users want to use a electronic dimme...
