Common faults and troubleshooting methods of oxidation high-frequency power supply（IGBT rectifier)
1、 Overload fault
When the oxidation high-frequency power supply is in operation, if the electrical appliances exceed the rated load of the power supply, overload faults will occur. At this point, the power will automatically shut down to protect internal electronic components, thereby avoiding circuit short circuits and damage caused by overload. To solve the overload fault, the following steps can be taken for troubleshooting:
1. Check if the electrical appliances are overloaded, and if so, replace them with appliances that meet the specifications;
2. Determine if the rated load of the power supply is correct. If it is incorrect, replace it with a power supply that meets the requirements;
3. Check if the power supply is installed correctly. If there are any abnormalities, the power supply needs to be reinstalled.
2、 Short circuit fault
If the oxidation high-frequency power supply encounters a circuit short circuit during operation, it will immediately stop working. This is because the power supply found that the circuit load was too high and the current exceeded the rated value, resulting in a short circuit in the circuit. To solve the short circuit fault, you can try the following methods:
1. Check if the circuit connections are loose, and if necessary, reconnect them;
2. Check for foreign objects in the work environment and remove them if necessary;
3. Check the internal electronic components of the power supply and replace them promptly if they are damaged.
3、 High temperature fault
During the use of the oxidation high-frequency power supply, high temperature faults may occur due to factors such as machine vibration and temperature environment. At this point, the power supply needs to automatically stop running to protect the internal electronic components from damage. To troubleshoot such faults, the following steps can be taken:
1. Check if the environment around the power supply meets the requirements. If replacement is needed, it should be done promptly;
2. Check the cleanliness of the internal heat sink of the power supply. If cleaning is necessary, the heat sink needs to be cleaned;
3. Check if the process parameters of the power supply are correct. If changes are needed, they need to be reset.
In short, oxidation high-frequency power supplies may encounter various malfunctions during use. Therefore, when using a power supply, it is necessary to have a certain understanding of various faults in order to promptly troubleshoot and solve problems
What is the advance of IGBT anodizing rectifier?
1. Improve power conversion efficiency
High frequency power technology can improve the conversion efficiency of power supplies because the switching speed of high-frequency currents is faster, which can convert AC electricity to DC electricity faster and reduce energy loss.
2. Reduce power loss
High frequency power technology can reduce power losses because the alternating period of high-frequency current is shorter, which can complete power transformation, rectification, filtering and other processing more quickly, thereby reducing energy loss of the power supply.
3. Reduce the size of the power supply
High frequency power technology can reduce the size of power modules because high-frequency currents have higher frequencies and require smaller components, allowing for more components to be placed in the same space and achieving smaller power module designs.
The difference between high-frequency power supply （IGBT rectifier) and thyristor power supply(SCR rectifier)
1、 Overview and Characteristics of High Frequency Power Supply
High frequency power supply is a type of power supply with a relatively high frequency, typically operating above 20kHz. A high-frequency power supply consists of a high-frequency transformer and a capacitor, which can generate high-voltage power through high-frequency oscillation. Compared to thyristor power supplies, high-frequency power supplies have the following characteristics:
1. High efficiency: High frequency power supplies transmit almost no energy loss, making them more efficient than thyristor power supplies.
2. Small size: Due to the high operating frequency of high-frequency power supplies, their components can be smaller, and the overall volume of the power supply is smaller than that of thyristor power supplies.
3. Wide range: High frequency power supplies are suitable for various occasions, such as production lines, laboratories, medicine, and other fields.
2、 Overview and Characteristics of Controllable Silicon Power Supply
A thyristor power supply is a type of power supply that uses thyristor devices for control. Its principle is to control the output power of the power supply by changing the conduction time of the thyristor devices. Compared with high-frequency power supplies, thyristor power supplies have the following characteristics:
1. High energy consumption: In the process of transmitting electrical energy through thyristor power supply, there will be certain energy loss, which is more energy consuming than high-frequency power supply.
2. Good stability: Due to the use of thyristor devices to control the output power of thyristor power supplies, their output voltage stability is relatively good.
3. Narrow application scenarios: Controllable silicon power supplies are usually used in fields such as aviation and railways that require high power supply and have a narrow application range.
3、 Comparison between High Frequency Power Supply and Controllable Silicon Power Supply
1. Application scenarios: High frequency power supplies are suitable for various occasions and can have a wider input range, while the application scenarios of thyristor power supplies are relatively narrow.
2. Energy efficiency ratio: Currently, the energy efficiency ratio of most high-frequency power supplies is higher than that of thyristor power supplies, so high-frequency power supplies are more popular in some occasions with high energy requirements.
3. Stability: Due to the good output voltage stability of thyristor power supplies, they are more suitable for applications or fields that require high power supply stability.
high-frequency power supplies and thyristor power supplies have their own characteristics, and the appropriate power supply type should be selected according to specific needs.
