Working principle of electroplating power supply
Publisher: Administrator Date：2021-03-05
Power generators can convert mechanical energy into electrical energy, and dry batteries can convert chemical energy into electrical energy. The generator and battery themselves are not charged. Their two poles have positive and negative charges respectively. The positive and negative charges generate voltage (current is formed by the directional movement of charges under the action of voltage). The charge conductor is inherently present, and it needs to generate current. You only need to add voltage. When the two poles of the battery are connected to the conductors, the positive and negative charges are released in order to generate current. Dry batteries, etc. are called power sources. The device that converts alternating current into direct current through a transformer and a rectifier is called a rectifier power supply. The electronic device that can provide a signal is called a signal source. The transistor can amplify the signal sent from the front, and transmit the amplified signal to the subsequent circuit. The transistor can also be regarded as a signal source for the following circuit. Rectified power sources and signal sources are sometimes called power sources. A power supply is a device that provides power to electronic equipment, also known as a power supply, which provides the electrical energy required by all components in the computer. The size of the power supply, whether the current and voltage are stable, will directly affect the performance and service life of the computer. The computer power supply is a closed independent component installed in the main box. Its function is to change the AC power to 5V, -5V, +12V, -12V, +3.3V and other stable DC power through a switching power supply transformer to supply The system version, floppy disk, hard disk drive and various adapter expansion cards in the main box are used for system components. In layman's terms, one power supply is broken, and another backup power supply replaces its power supply. The availability of hardware can be enhanced by providing battery backup for nodes and disks. HP-supported uninterruptible power supplies (UPS), such as HP PowerTrust, can guard against instantaneous power loss. The connection between the disk and the power supply circuit should be such that the mirrored copies are connected to different power sources. The root disk and its corresponding nodes should be powered by the same power circuit. In particular, the cluster lock disk (used as an arbiter when reorganizing the cluster) should have redundant power, or it can be powered by a power source other than the nodes in the cluster. An HP representative can provide detailed information about the cluster's power, disk, and LAN hardware layout. At present, many disk arrays and other rack-mounted systems contain multiple power inputs. They should be deployed as different power inputs on the equipment connected to independent circuit equipment with two or three power inputs. In this way, in general, as long as there is If there is no more than one faulty circuit, the system can continue to operate normally. Therefore, if all hardware in the cluster has 2 or 3 power inputs, at least three independent circuits are required to ensure that there is no single point of failure in the circuit design of the cluster.

SXD-PWH series high-frequency switching power supply is a high-frequency switching power supply originally developed and successfully developed by our factory. It has a completely different working principle from the previous power frequency silicon controlled rectifiers. It generates low voltage and large current output through the input high voltage AC rectifier-high voltage filter-high voltage and high frequency regulation-low voltage and high frequency rectification. Its working principle determines that the power supply has higher conversion efficiency and higher current conversion efficiency than the silicon controlled rectifier. Power factor has become the preferred power supply product for many customers. Using this power supply can significantly reduce production costs and improve product quality. Compared with thyristor power supplies, production energy consumption can be reduced by 20%-30%, bringing considerable economic benefits to users . The power supply is small in size and light in weight (water-cooled is smaller than air-cooled), and it is very easy to install and use, which can save valuable production space for users. The main power high frequency transformer of SXD-PWH series high frequency switching power supply adopts imported nano crystal/ultramicro crystal, high permeability material as the magnetic core, which is small in size and high in efficiency.
High-frequency and high-power switching components (IGBT), power drive modules, and three-phase bridge stack are all selected from international famous brands such as Mitsubishi, Fuji, Freetech, Germany, etc. The circuit board components are all selected from famous manufacturers. Our company has developed a unique water-cooled high-frequency electroplating power supply (patent pending), which has better cooling effect, anti-salt spray acidification, increases the service life of the power supply in harsh environments, and has stronger corrosion resistance, which can greatly extend the service life of the power supply. The water discharged from the machine is free of any pollution and can be recycled and reused!
SXD-PWH series high frequency switching power supply has complete protection functions: input phase loss, undervoltage, overheating, overcurrent, short circuit protection, safe and reliable.
The SXD-SS-SR series high frequency switching power supply has the following advantages compared with the ordinary switching power supply in the same market:
1. The full-bridge phase-shift soft switching control method is adopted to eliminate the switching stress to the greatest extent, and the world's latest full-bridge soft switching control IC is adopted, which has the function of automatically adjusting and setting the trigger pulse sequence parameters to achieve the best IGBT switching time. The IGBT switching loss is minimized, and the IC with its own synchronous rectification drive function is adopted, which simplifies the synchronous rectification drive circuit. Make its work more stable and reliable.
2. Adopt advanced logic interlock control circuit to eliminate pulse false trigger and overcome bridge arm short circuit.
3. It eliminates the magnetic bias problem, mainly in the following two aspects:
(1) The primary transformer of the main transformer uses series blocking capacitors
(2) Increase the bias magnetic automatic correction circuit
4. Using foreign original imported MOS tubes as secondary side rectifiers, and using advanced and reliable special imported synchronous rectification module technology, the efficiency of this high-frequency switching power supply is about 15% higher than that of similar ordinary rectifying switching power supplies under low voltage and high current conditions.
