High Voltage Power Supply Short Circuit Current Protection Mechanism

In electronic equipment, high voltage power supply is a very common power supply. Some equipment using high voltage power supplies, such as generator speed regulators, may not work properly if the high voltage power supply fails. In order to protect the safe operation of high voltage power supplies, here we will introduce the protection mechanisms of transient short circuit current and normal short circuit current.
 
Transient short circuit current protection mechanism
 
Transient short circuit current refers to the high current generated by instantaneous short circuit. If the transient short circuit current exceeds the rated current of the high voltage power supply, it will damage the electronic components and some electrical components of the power supply, thereby affecting its normal operation. In order to protect the high voltage power supply, a special transient short circuit current protection mechanism has been developed.
 
The core of this protection mechanism is that when the high voltage power supply is short-circuited and the short-circuit current exceeds the rated current, a signal sent by the controller will be triggered. This signal will trigger the protection mechanism to limit the magnitude of the short-circuit current. This mechanism contains the actual output voltage output by the high voltage power supply and the corresponding signal. In the protection mechanism, this voltage and signal are analyzed to limit the short-circuit current, thereby protecting the high voltage power supply.
 
Normal short circuit current protection mechanism
 
The normal short circuit current refers to the current generated when some faults occur in the internal circuit of the power supply under normal use conditions. The normal short circuit current is usually very small, but if it exceeds the rated current of the power supply, it will cause damage to the power supply. In this case, the normal short circuit current protection mechanism can play a role.
 
The core of the normal short circuit protection mechanism is to limit the output current of the power supply through a current control circuit. If there is a fault in the internal circuit of the power supply, its output current will be limited to avoid excessive short circuit current. In addition, high voltage power supplies can also install current protectors to monitor the magnitude of the output current. Once the current exceeds the rated value, the current will be automatically cut off, thereby protecting the high voltage power supply.
 
In summary, transient short circuit current and normal short circuit current are very important issues in the use of high voltage power supplies. Through the transient short circuit current and normal short circuit current protection mechanisms, we can protect the normal operation of high voltage power supplies, avoid excessive short circuit current of power supplies, and thus affect their normal use.
