- Q:I have an output voltage of 3V, 500MA switching power supply, would like to change the output voltage of 5V charger specific parts to change the value, such as feedback resistor, switch transformer (there are two).
- The 3V output into 5V output is relatively easy, and perhaps directly change the proportion of feedback resistance can be, and then not, the transformer output plus a few turns also get. But the adapter to switch the power into a charger is too much trouble, because the charging current is the need for current limiting, or battery life will be greatly reduced or even directly burned. So be careful Look at your circuit diagram is an electronic transformer schematic, is generally used to do energy-saving lamp power supply, the output is about 40KHZ AC, in order to change its output voltage can only be changed by changing the EE19 transformer turns
- Q:What is the impact of the refrigerator on the refrigerator?
- This may not seem to control the refrigerator to open the machine, will inevitably cause some food to reach the required temperature, that is, the refrigerator did not reach 5 degrees, the man-made downtime.
- Q:I copied a circuit board, 7W switching power supply, line and the original circuit is exactly the same, that is slightly different alignment, no power after the output. I made two boards, are the same ask, ask the master, where is the problem? How to deal with?
- There may be a transformer problem, you have measured the inductance of two transformers is the same, flyback switching power supply is the core to stay in the gap.
- Q:We use the switching power supply is 220v-48v, the room has air conditioning, air conditioning power in 6kw or so, the total power of this room in 17kw, DC current is 60A, the room has two tubes. Now do not know how much switching power supply losses, these devices may have 17kw power? This is the 17kw power meter on the show. Who heroes help me.
- The energy meter shows "power", not power. You want to know the actual shaft power of the electrical, the former level is connected to the AC power table, rather than the energy meter. Switching power supply upstairs said it was right.
- Q:Switching power supply, starting resistor is very hot, no output. What is the reason.
- If it is the circuit, to check the chip's operating point has not met the requirements, but also to check the over-sampling voltage is not high, Vref voltage is wrong, RtCt circuit is no problem.
- Q:24V 1A switching power supply how to output 0-10V I <1mA adjustable signal ah
- You call the power of external control, your switching power supply voltage is fixed, it can only 0-10V, control 0-24V, the current to buy a Hall sensor, corresponding to the output 1A,
- Q:Switching power supply circuit will ring what will happen
- There are two cases of voltage regulator sampling circuit will cause the voltage rise but the design of a good circuit protection is perfect when the switching power supply will immediately protect and stop working there is a switching power supply on the sleek ring design of the voltage requirements are not very There is a strict need for power to have a faster response speed and large output current, such as some of the power amplifier is now open-loop design
- Q:What is the basic principle of switching power supply?
- The exchange through the diode rectifier. Capacitor filter into DC, and then through the 1620KHz high frequency oscillation generator. Switch and high frequency switching transformer role, the DC into the required amplitude of the high frequency pulse voltage. And finally through the high frequency of the two poles to the high frequency pulse voltage rectification. Capacitance filter output required DC voltage. The output regulator is to rely on the output to remove the sampling voltage to adjust the oscillator frequency and pulse duty cycle.
- Q:Working principle of small switching power supply
- Small switching power supply works is to control the switching transistor through and turn off the time ratio, to maintain a stable output voltage of a power supply, switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. Switching power and linear power compared to the cost of both the output power increases with the growth, but the growth rate of the two different. Linear power costs at an output power point, but higher than the switching power supply, which is called the cost of reversal point.
- Q:The original circuit is in accordance with the 20K switching frequency design inductance, and now the switching frequency to 10K, do not know if this will be any problem? Inductance in the output of relatively large power, there will be buzzing sound, what is the reason?
- The The child's hearing limit is higher! You will change the transformer and so on. If it is home, there is a child to be careful! Will harm the child health!
