NX series hybrid solar inverter 12v
1 What is the basic working principle of a power supply?
A: Convert the input higher alternating voltage (AC) to the lower direct current (DC) required for PC operation by running high frequency switching technology.
2 What is the workflow of the power supply?
Answer: When the mains enters the power supply, it is first filtered by choke coils and capacitors to remove high-frequency clutter and interference signals, and then rectified and filtered to obtain high-voltage direct current. Then, the direct current is converted into high-frequency pulsating direct current through the switching circuit, and then sent to the high-frequency switching transformer to reduce the voltage. Then filter out the high-frequency AC part, so that the final output is relatively pure low-voltage DC for the computer to use.
3 What is the main function of EMI circuit?
Answer: The function of the EMI circuit is to filter out various interference signals coming from the power grid and prevent the high-frequency interference formed by the power switch circuit from disturbing the power grid. EMI is an important part of CCC certification.
4 What is a high voltage rectifier filter circuit?
Answer: The high-voltage rectifier filter circuit consists of a rectifier bridge and two high-voltage electrolytic capacitors. The function is to convert 220V AC mains into 300V DC.
