- Q: A DC / DC switching power supply input with UC3843 is a 24V power supply between two power supplies is up to 200M line now the situation is DC / DC power supply at no time when the load is measured at this time DC / DC power input It is actually less than 15V if the DC / DC power supply is loaded with about 10W and the 24V power supply output is adjusted to 27V or more when the DC / DC power supply is working In front of the wrong In the load when the 10W when the front power output is adjusted to 27V measured when the power input voltage is 14.5V or so when the no-load time is normal add another point With 10W when the front of the power output is adjusted to 27V below the two power between the current is significantly increased at this time into the DC / DC power supply voltage from 15V down to 6,7V looks more like the back of the power from Excited and DC / DC of this power supply in the 9V or so input conditions can work properly
- DC power supply inside the capacitor caused by leakage can not bring the load, I have previously repair, replace the filter capacitor to solve the problem. Leakage, can only replace, you add more capacitors is useless.
- Q: Give you a switch on how to look at it is isolated and non-isolated?
- Isolated for high-pressure exchange, a transformer, the transformer is mostly core, but also useful magnetic ring Non-isolated generally low-voltage direct current, no transformer, there is an inductor, high-power multi-purpose magnetic ring, low-power inductance with more
- Q: As shown below, I used a switch chip tny276pn, optocoupler pc817, regulator source tcl431 and some small components (capacitors, resistors, etc.) designed a 5Vdc switching power supply. Transformers are custom, according to the flyback type, 132kHz, 85 ~ 265Vac parameters to do. The upper right corner of the picture p2 end is a 20-30 ohm coil, and now found that the input voltage dropped to 20Vac, 5Vdc was unstable, coil control of the magnet was to jump, I would like to 20Vac this parameter increased to 60 ~ 80Vac, So that the coil control of the magnet in the low voltage when the high jump, how should modify the circuit? Thank you.
- The maximum power of the power is 1.25W, the overall power supply power by 70% efficiency of 1.8W. In this case need to modify the transformer. To the place there are the following: 1, the transformer to increase the ratio; such as the original is 200: 5, now changed to 300: 5. Now want to do your request 60-80VAC input protection, you need the current transformer parameters to be calculated; 2, the transformer sensation increased; proposed to change to 4mH ~ 8mH. Once the two done, the protection voltage will rise.
- Q: What are the main components of the switching power supply?
- In which the transformer part has an auxiliary winding through the IC current voltage sampling to control the duty cycle of the switch to adjust the output current.
- Q: I made a switching power supply, using boost dc-dc transform, input 18V, output 30-36V variable. Found that the output voltage has 300mv ripple and 1V burr. Has been added 10mh inductance and 6600uf capacitor filter. Switch tube plus RCD buffer Output with choke and EMI filter,
- You said the burr is the overshoot Your inductance is not wrong? 10mH too big? Will it be 10uH wrong? In the out there, the overshoot is sure to exist, but this should be gone in the capacitor This has a lot to do with your measurement 1. Must be in the capacitance of the positive or the amount of load above, do not in the amount of inductance, there is no capacitance 2. With the oscilloscope, the ground connection will have a great impact on the measurement results you can move their own line of the line to see the extent of the test will certainly move The probe on the ground to try to short, the measurement results are correct The above two points to do, the measurement results should not be so big And to be honest, for the 30V output, there are 1V "glitches" that should be acceptable You can check the specifications of other switching power supply, this one usually 5%, 30V * 5% = 1.5V, 1V should be acceptable
- Q: Switching power supply maintenance methods can be divided into several steps
- ?2, the first step is completed, after the power is not working properly, and then to detect the power factor module (PFC) and pulse width modulation components (PWM), access to relevant information, familiar with the PFC and PWM module each foot function and Its modules work properly prerequisites.
- Q: Car cd with the battery all right, with a switching power supply speaker has a buzzing sound
- Voltage big bar, it should be between 12 volts to 15 volts,
- Q: What is the difference between DC regulated switching power supply and linear power supply?
- Switching power supply: high efficiency, small size, inertial components (inductance and smooth capacitance, etc.); Traditional power supply in turn is it, but the traditional power of the biggest advantage is the small noise, harmonic interference is small.
- Q: How to constant voltage switching power supply into a constant current, how to rectification ?
- In fact, from the control point of view, the constant current source and constant pressure source is the same, but the sampling point is different; also said that the control object or the target is different, and the constant pressure source to constant current source only need to pass the current Sampling Resistor Sampling Current
- Q: Will the switching power supply fake load how to calculate?
- As for the choice of parameters, one is enough resistance power, the second is the resistance, which can make the output stability of the resistance in the small point on the line, too small will increase the no-load loss, affecting efficiency, too much to play a role.
