inverter 12 v to 220 v pure sine wave 3kw

    The anti-surge capability of the inverter is also called overload capability. #inverter 3000w     In practical applications, many loads require large current or power when starting, such as various motors, refrigerators, air conditioners, washing machines, and water pumps. #inverter 24v 220v 5000w     There is a degaussing coil inside, which also requires a large current when starting up. #inverter off grid     If the inverter does not have this surge immunity, it may cause the inverter to trip. The inverter should have sufficient margin to ensure that the load can start reliably.

2. Voltage start circuit: Receive the working enable voltage ENB. When ENB is 3V, the panel's backlight tube will light up, indicating that the inverter is in normal working condition.

　　3, PWM controller: Receive Panel current control DIM signal, complete the functions of overvoltage protection, undervoltage protection, short circuit protection, pulse width modulation, etc.

　　4. DC conversion circuit: It is composed of MOS switch tube and energy storage inductor. When 12V DC voltage VIN is received, the MOS tube starts to switch, so that the DC voltage charges and discharges the inductor cyclically to obtain AC voltage.

　　5. LC oscillation and output circuit: to ensure the 1600V voltage required when the lamp is started, and to reduce the voltage to 800V after it is started.

Have a nice day!
