Advantages of customized switching power supply

Speaking of the switching power supply and medical equipment power supply of Simytek Electronic Technology power supply manufacturer, the advantages of the printer switching power supply are as follows

1. Small size and light weight.

Switching power adapter adopts high frequency transformer, which has high working frequency and small size. Because the power dissipation on the switching MOS tube is greatly reduced, the large heat sink is omitted.

2. Wide range of voltage regulator.

The output voltage of the switching power adapter is regulated by the duty cycle of the excitation signal. The voltage variation of the input signal can be compensated by frequency modulation or width modulation. In this way, when the power frequency grid voltage changes greatly, it can still ensure a stable output voltage. So the switching power supply adapter voltage range is very wide and the voltage stabilization effect is very good. In addition, there are two ways to change duty ratio: pulse width modulation and frequency modulation.

3. Low power consumption, high efficiency.

In the switching power adapter circuit, the switching MOS tube under the excitation signal, it alternately works in the on-off and cutoff on-off switching state, the conversion speed is very fast, the frequency is generally more than 50kHz, in some advanced switching power lines, it can do several hundred or nearly mega Hz. This makes the switching MOS tube power consumption very small, the efficiency of the power supply can be greatly improved, its efficiency can reach 92% or above.
