1000w-6000w Single Phase Inverter

FI series :1000w-6000w single phase inverter

The main structure and working principle of laser power supply:

1. Power filter and rectifier circuit: It contains power RF filter and high-voltage ground point protection.

The function of the power supply RF filter is to suppress the RF conduction interference to the power grid when the laser power supply is running. Like the usual switching power supply, this module can effectively reduce the large current impact at the moment of startup, and also greatly reduce the moment of startup from the source. Interference, which is more sensible and effective than passively enhancing RF waves.

The function of high voltage discharge protection to ground is discharge protection. When the power supply is working, it is necessary to prevent the power-on moment and other unfriendly behaviors that damage the power supply. It is required that the power supply itself should also do its own protection work. The high-voltage ground discharge protection can effectively avoid the main circuit and the laser power supply. Safety of control circuits and auxiliary power.

2. Converter main circuit: DC/AC converter, high voltage package, working status display, drive circuit.

DC/AC converter: Using principles such as electromagnetic induction to convert alternating current into direct current of a specific voltage.

High-voltage package: The high-voltage package can effectively keep the peak voltage in the conversion circuit, avoid the voltage exceeding the limit between the transistor set and the emitter, and ensure the stability and reliability of the working process.

Working status: Displays whether the conversion circuit is working normally.

Drive circuit: The drive circuit can be understood as a push-pull switching amplifier output by a transformer. When there is no penalty voltage signal at the input, the base voltage of the transistor is lower than the emitter, and the transistor is turned off. When a level appears at the base of a transistor, the transistor is turned on. The lines work together to provide stable reliability.
