High Frequency inverter RO4250B fr4 Pcb

What is a high frequency inverter?

The high-frequency inverter uses the DC/AC conversion technology of the High frequency board to invert low-voltage direct current into high-frequency and low-voltage alternating current. After being boosted by a high-frequency transformer, it is rectified by a high-frequency rectifier filter circuit to usually above 300V The high-voltage DC power is finally used by the power frequency inverter circuit to obtain 220V power frequency AC power for the load. Advantages and disadvantages of high-frequency inverters: high-frequency inverters use small, light-weight high-frequency magnetic core materials, which greatly increases the power density of the circuit, and makes the no-load loss of the inverter power supply small. The variable efficiency has been improved. Usually the peak conversion efficiency of high-frequency inverters reaches more than 90%. But it also has significant shortcomings. The high-frequency inverter cannot be connected to a full-load inductive load, and its overload capability is poor.
The PCB board of the inverter includes a PCB board body and wiring terminals arranged on the PCB board body, the PCB board body is provided with two sets of transformers, and the back of the PCB board body is provided with two sets of current-carrying copper The two sets of the current-carrying copper sheets are respectively connected to the High frequency board of the two sets of transformers on the PCB board body. The PCB board of the inverter of the present invention has the advantage of improving the current-carrying capacity of the PCB board At the same time, the conversion efficiency of AC and DC is improved, and the safety of power supply is improved.
