Using this larger AC coupling capacitor value is good practice when dealing with the large DC shifts associated with the SMPTE pathological signals. 5. For 800 mVP-P output, change the RREF resistor from 1.91 kΩ connected to ground to 750Ω connected to VCC. For 1.0 VP-P output, ...
"Inrush current or switch-on surge refers to the maximum, instantaneous input-current drawn by an electrical device when it is first turned on. Because of the charging current of the APFC capacitor(s), PSUs produce large inrush-current right as they are turned on. Large inrush current can...
The SiC MOSFET intelligent power integration module comprises a base board, an AC power terminal, an input terminal, a first control terminal and a second control terminal, wherein a SiC MOSFET power unit, a bus capacitor, a first drive circuit and a second drive circuit are integrated on ...
12.Dimmable LED light unit according to claim 11, wherein the power factor correction circuit is adapted to receive AC power with an AC voltage of between 100 V and 150 V and with an AC current of between 150 mA and 300 mA and wherein the buffer capacitor of the power factor correction...
The variety of driver circuits that can be used in LED lamps is discussed in [19], which suggests avoiding the use of an electrolytic capacitor, which has a very short lifetime, in driver circuits to improve the life of these circuits. The use of an integrated double buck-boost converter...
