1.概念: DC-DC指直流转直流电源(Direct Current)。是一种在直流电路中将一个电压值的电能变为另一个电压值得电能的装置。如,通过一个转换器能将一个直流电压(5.0V)转换成其他的直流电压(1.5V或12.0V),我…
Battery: the essential input data are the output voltage and the maximum short-circuit current. Capacity can be indicated for information. Rectifier/battery assembly: the input data is a combination of that of the two constituent elements. The following receivers are managed in the DC module: Plu...

DC stands for Direct Current, although it is often called “DC Current”. DC current is defined as a unidirectional flow of electric charge. In DC current, the electrons move from an area of negative charge to an area of positive charge without changing direction. This is unlike alternating ...

Key components needed in a switch design include inductors and capacitors for energy storage and diodes to control the direction of currents. As the switch is cycled on and off, energy is stored and released by the magnetic field of the inductor. Switching regulators can efficiently...
One nice feature of an electric circuit is that you can install a switch in the circuit to turn the power on or off when you want. Note: Although DC electric current is designated as going from positive (+) to the negative (−) area, this convention for the motion of electricity was...
