- Q:Switching power supply OLP and OCP
- OLP is overload protection, to prevent the main power lines due to overload caused by overheating protection and installation of overload protection equipment.
- Q:Direction switching power supply
- Modularity is the overall trend of switching power supply development, modular power can be used to form a distributed power system, can be designed as N + 1 redundant power supply system, and to achieve parallel capacity expansion. For the switching power supply operation noise this shortcomings, if the pursuit of high frequency of its noise will also increase with the use of part of the resonant conversion circuit technology, in theory, can achieve high frequency and can reduce noise, but some The practical application of resonant conversion technology still has technical problems, so it is still necessary to carry out a lot of work in this field, so that the technology can be practical.
Power electronics technology innovation, so that the switching power supply industry has a broad development prospects. To speed up the development of China's switching power supply industry, we must take the road of technological innovation, out of the Chinese characteristics of the joint development of production and research, for the rapid development of China's national economy to contribute.
- Q:Switching power supply, what is the hard switch? What is a soft switch?
- Hard switch is the switch in the inherent cycle, and the soft switch is different, is the use of the role of oscillation in the voltage and current is zero to open and close the switch, which greatly reduces the loss on the switch, The efficiency of the.
- Q:What is called switching power supply? Such as commonly used circuit
- Power products are widely used in industrial automation and control, military equipment, scientific research equipment, LED lighting, industrial equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and other fields
- Q:Switching power supply, starting resistance is very hot, no output
- You ask the question is the common problem of switching power supply, you have to study the power schematic diagram! Practice basic skills.
- Q:How to choose the switching power supply frequency?
- Since I do not have power, the following is only a personal view
Internal: 1: depends on your topology and power level 2: the choice of IC and switch operating frequency and can withstand the thermal upper limit external: 3: circuit other power device frequency range 4: assigned to the various devices Limit the temperature is acceptable, in terms of volume, efficiency, cost, heat, system stability, etc., the parties weigh the next value, then the frequency of the better the common frequency as small, the corresponding magnetic device volume will be relatively large, and Frequency is large, the device is small, but the switch loss, of course, core loss is also large, unacceptable.
If there are problems please go to the big bit forum to ask me, if you help the busy also hope to adopt the answer!
- Q:12V switching power supply, which brands through 3C certification?
- 3C certification is China's mandatory product certification, where the directory in the 3C certification required to be certified products need to be certified to the factory sales, import and use in business activities.
The PC power supply belongs to the directory to be mandatory certification of products, so in the market of formal power products will be mandatory through the 3 C
Such as HuntKey, Colorful, Great Wall, GOLDENFIELD, TT and Cool Cold's mainland sales products.
- Q:What is off-line switching power supply
- Switching power supply isolated, non-isolated two, where the "isolation", "non-isolated" are in terms of the grid. Isolated switching power supply, also known as off-line (off-line) switching power supply, which belongs to AC / DC converter, which is characterized by high-frequency transformer and optocoupler feedback circuit to achieve the isolation of the output voltage and the grid, the switching power supply Specified safety regulations. Isolated switching power supply is safe, but the circuit is complex, the cost is higher; non-isolated switching power supply circuit is simple, but the security is poor. Should be based on the design of the use of switching power supply and safety norms to choose. For example, according to the relevant standards, some white goods (such as home air conditioners, dishwashers, rice cookers, refrigerators, household electric heaters, etc.) internal control power, allowing the use of non-isolated switching power supply to reduce costs, The provisions prohibit the user to repair, so to avoid the occurrence of security incidents.
- Q:Dimming mode, the switching power supply creak sound
- the human ear should not reach this sensitive range.
- Q:Power amplifier with a good power or good switching power supply?
- Generally believed that the best R-type transformer, ring type, switching power supply transient response is not enough, open-loop can be used, but the effect is poor.
Now there are dedicated power amplifier switching power supply, the main features are: resonant switch circuit; (and the same effect as the transformer sine wave effect, very little interference, the car amplifier has been using resonant circuit). Open-loop output, not regulated output, no response time. Heavy weight, high efficiency and so behind are nonsense
Nowadays, our products are exported to numerous countres, like US, Australia, UK, etc. Successful improvements on technical processes and professional customer services have been recognized by more and more new or old customers. We hardly receive any negative feedback from customers. Our products so far have catched up with the consistency with world standard .
