The switching power supply mainly includes an input power grid filter, an input rectification filter, an inverter, an output rectification filter, a control circuit, and a protection circuit. Let's take a look at their respective roles: Input Grid Filter: It is used to eliminate interference ripple ... read more
Our common power sources, including power adapters and chargers, are all switching power supplies. The switching power supply is a power supply that maintains a stable output DC voltage by controlling the ratio of the time period in which the switching transistor is turned on and off. The switching ... read more
The complete naming of wires and cables is often complicated, so people sometimes use a simple name (usually the name of a category) in combination with the model specification instead of the full name, such as "low voltage cable" for all plastic insulated power of 0.6/1kV class. cable. The wire and... read more
