The characteristic of linear DC power supply is that its power device regulator works in the linear region
Phenomenon 1: Output voltage without current, or current without voltage
Depending on the size of the current passing through the human body, it has nothing to do with alternating current or direct current.
As for the choice of DC power supply, is it a transistor linear DC power supply or a SCR DC power supply or a switching power supply?
The power operation power supply in power plants and substations now adopts DC power supply, and DC screen is used to supply this kind of DC power supply. It provides power for controlling load and power load, as well as lighting load of DC accident,
From the application level, automotive electronics can be divided into two categories: electronic control system and on-board electronic devices.
The filter circuit realizes the filter by utilizing the different impedance of reactance components to AC and DC.
Electrical circuits need DC power supply to provide energy when they work.
Working parameter table of typical AC voltage stabilized power supply
We know that in the installation of electrical appliances, first use the pen to distinguish the fire line from the zero line.
