The DC regulated power supply switching power supply is converted into high frequency pulse current
GVDA DC regulated power supply switching power supply is converted into high-frequency pulse current, and the output voltage or current is changed by releasing electric energy through the characteristics of inductance and capacitance, and electric energy is stored in the inductance and capacitance. It utilizes the linear characteristics of the components. The linear DC regulated power supply has no high-frequency pulses and storage components, and realizes the stability of voltage and current through the feedback control input when the load changes.
Carrier energy-saving switching DC stabilized power supply has the advantages of high efficiency, wide output voltage, low loss, low pressure, etc., and can also be improved, but the AC ripple is slightly larger, and it has certain electromagnetic interference and noise. The linear DC regulated power supply has the advantages of high stability, simple circuit, small ripple, high reliability, low interference, and easy multi-output continuously adjustable products.
It can only step down, not step up. In addition, when the input and output voltage difference and load current are large, the efficiency is low, the loss is large, and the gross heat is obvious. Low-power switching DC regulators are mainly used in electrical appliances, IT and other fields, such as computers, color TVs, printer power supplies, mobile phone chargers, cameras, video and other electronic equipment; high-power switching power supplies can be used in various electronic equipment. Linear DC regulated power supply can be used in scientific research units, laboratories, industrial production lines, colleges and universities, electrolysis, electroplating, charging equipment, etc.
