- Q:Classification of DC Regulated Power Supply
- On the two, one is the switching power supply, one is analog power,
- Q:What is the main domestic DC power supply brand?
- Yes, compared to some of the same international quality of the power supply is still very cost-effective,
- Q:How to describe the power supply voltage accuracy
For example, there are 100 dollars to be distributed to 7 individuals assigned to the accuracy of 1% in terms of the proportion of money that is to say the exact value of the yuan points to reach the points
- Q:Why study DC power supply circuit
- The performance of some devices has a direct relationship with the voltage, the voltage changes will cause the equipment performance stability or output parameters. So in some specific equipment before adding power supply, DC power supply is about to convert AC power to a stable voltage DC power supply.
- Q:What is AC regulated power supply
- AC power supply is the AC power supply is stable AC power.
DC power supply is DC power supply
- Q:What is a linear regulated power supply
- According to the adjustment of the working state of the tube, we often put the power supply is divided into two categories: linear power supply and switching power supply. In addition, there is a small power supply using a regulator.
- Q:The main reason for the instability of the output voltage of the regulated power supply
- The reason why the output voltage stability of the DC regulated power supply is poor.
(1) Maximum input voltage
Is to ensure that the DC power supply safe operation of the maximum input voltage.
(2) the maximum output current
Is to ensure that the safe operation of the regulator to allow the maximum output current.
Rectified filter output after the DC voltage, although the degree of smoothness is good, but its stability is still relatively poor.
- Q:What is the DC load power supply load characteristic curve, how to measure
- DC load power supply load curve, that is, the relationship between the output voltage and load resistance curve (the greater the resistance the higher the output voltage), is determined by the output power of the power supply itself.
On the improvement that depends on what you do the circuit, and now the more popular is the switching power supply, is to control the duty cycle, the first output square wave, and then after the filter circuit. If you want to have a voltage regulator circuit, the feedback circuit is based on the load to adjust the power duty cycle.
- Q:Switching power supply and DC power supply difference
- Just say it! 1 switching power supply regulator in the open and closed state of the linear power supply work in the amplification zone (specific cut-off, saturation, amplification, non-saturation in the transistor and MOSFET in the name difference) 2 switching power supply is to change the duty cycle to adjust the output According to the specific topology design can achieve step-up and step-down and linear power supply through the output sampling and reference voltage to compare the amplification to adjust the regulator tube can only step down 3 switching power supply efficiency is generally 80% of some can reach 95% linear power work to enlarge The device voltage drop is very large loss and therefore the efficiency of the lower volume of large 4 linear power supply input voltage adjustable range is relatively low
The advantages of linear power can be seen from these points: Wen Bo, noise low cost of low technology mature! Hope it helps you!
- Q:Is there a voltage regulator for CNC machine tools?
- It is useful to use a voltage regulator for CNC machine tools, but it is not necessary. The use of regulators for CNC machine tools, especially in China's power grid conditions are good. Because China's grid voltage is not stable, which on the CNC machine tool drive and system stability have a great threat.
