Ups and high frequency switching power supply
The difference between high frequency and power frequency lies in an isolation transformer
UPS is an acronym for uninterruptible power supplies. Is named according to the application of the product.
High-frequency switching power supply, refers to the use of power switching devices, at high frequencies through the converter for energy conversion power. Is based on the technology used to name the product.
Now the UPS is basically using high-frequency switching technology to achieve. So UPS is also a high-frequency switching power supply.
UPS and high-frequency switching power supply The main difference:
High-frequency switching power supply, refers to the use of power switching devices, at high frequencies through the converter for energy conversion power. High-frequency switching power supply (also known as switching rectifier SMR) through the MOSFET or IGBT high-frequency operation, the switching frequency is generally controlled in the 50-100kHz range, to achieve high efficiency and miniaturization.
UPS is the uninterruptible power supply, there are batteries and inverter circuits and control circuit, when the mains power supply is interrupted, the UPS control circuit will detect and immediately start the inverter circuit work, so that the output of 220V AC, On the use of electrical appliances continue to work for some time, so as to avoid the loss of electricity caused by interruption.
Switching power supply is 220V AC, into the required DC it can have multiple sets of DC output, the main rectifier filter circuit, the control circuit, because of its high efficiency, small size, well protected, widely used in electronic equipment. Such as computers, television and so on.
