The membrane panel device is the core component of the membrane panel converter and is expensive. Therefore, the protection measures must first ensure the safe and reliable operation of the membrane panel device. In addition, the load of membrane panel converters or membrane panel power supplies generally contains a large number of highly integrated devices, which generally have poor resistance to electricity, heat and shock. Therefore, the protection of membrane panel converters should be Take into account the safety of itself and the load.
Membranepanel converters or membrane panel power supplies may be damaged or affect their performance and reliability due to fluctuations in input voltage, external load failures, and their own anomalies. Therefore, in order to make the membrane panel converter system and the load work safely and reliably, it must have complete protection functions. To this end, researchers have proposed various types of protection schemes and protection circuits for different protection needs.
At present, there are many types of protection. In addition to the aforementioned overcurrent protection, overvoltage protection, undervoltage protection and overheating protection, there are also polarity protection, program protection, and overpower protection. Since there are many types of membrane panel converters or membrane panel power supplies in Dongguan Silicone Key Factory, and their uses are different, the requirements for protection are also different, and the protection settings should be determined according to specific requirements.
After the protection circuit is added to the switching converter or the membrane panel power supply, it is bound to increase the components, which in turn will affect the reliability of the system. Therefore, the reliability of the protection circuit itself must be high to improve the reliability of the entire system. This in turn increases the mean time between failures (MTBF) of the membrane panel converter itself. This requires tight protection logic, simple circuits, and minimal components. In addition, the maintenance degree of the failure of the protected circuit itself should be considered to ensure the normal operation and high reliability of the power supply.
