The main reasons for the increase in inverter no-load current include aging of internal electronic components, improper protection circuit settings, and short circuit at the output end.
1. Aging of internal electronic components: As the use time increases, the electronic components inside the inverter will have problems such as loss and leakage, which often lead to an increase in the inverter no-load current. Therefore, when choosing an inverter, you should pay attention to quality, perform regular maintenance, and replace aging components in time.
2. Improper protection circuit settings: There are many protection circuits inside the inverter, such as overload protection, short circuit protection, overtemperature protection, etc. If these protection circuits are improperly set, such as the overload protection circuit is set too low, the inverter will be mistaken for an overload state during normal operation, so that the protection circuit will automatically start, causing the inverter no-load current to increase.
3. Output short circuit: When the output end of the inverter is short-circuited, the inverter cannot work normally. At this time, the current will become very large, resulting in an increase in the inverter no-load current. When the inverter output is short-circuited, the fault should be eliminated or the inverter should be replaced in time.
In summary, there are many reasons for the increase of inverter no-load current. We should analyze them from the above aspects and take corresponding measures to reduce the inverter no-load current and protect the normal operation of the inverter.
