One, the nature of the different
1, DC regulated power supply: can provide a stable DC power supply for the load of electronic devices.
2, switching power supply: a high-frequency power conversion device.
Two, different uses
1, DC regulated power supply use:
DC regulated power supply is widely used in national defense, scientific research, colleges and universities, laboratories, industrial and mining enterprises, electrolysis, electroplating, DC motors, charging equipment.
(1) It can be used for the aging of various electronic equipment, such as PCB board aging, home appliance aging, all kinds of IT products aging, CCFL aging, lamp aging.
(2) It can be used for the aging and testing of electronic components which need automatic timing, power-off and automatic cycle counting.
(3) Electrolytic capacitor pulse aging.
(4) Precision test of resistors, relays, motors and so on.
(5) Complete machine aging; electronic component performance test, routine test.
2, switching power supply use:
Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electric power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps and lanterns, communications equipment, audio-visual products, security monitoring, LED light tape, computer chassis, digital products and instruments and other fields.
Expanded Information:
The working process of a switching power supply is easy to understand. In a linear power supply, the power transistors are allowed to operate in a linear mode. Unlike linear power supplies, PWM switching power supplies let the power transistors work in on and off state.
In these two states, the volt-ampere product added to the power transistor is very small (in the on-state, the voltage is low and the current is high; in the off-state, the voltage is high and the current is low)/The volt-ampere product on the power device is the loss incurred on the power semiconductor device.
