What are the advantages of non-isolated power supply?(2)

(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;

rectangular wave of 20 kHz.
Due to the poor working conditions of the welding machine power supply and frequent short-circuit, arcing and open-circuit changes, the working reliability of the high-frequency inverter rectifier welding machine power supply has become the most critical issue and the most concerned issue by users. . The microprocessor is used as the relevant controller of pulse width modulation (PWM), and through the extraction and analysis of multi-parameter and multi-information, the purpose of predicting various working states of the system is achieved, and then the system is adjusted and processed in advance to solve the problem. The reliability of high-power IGBT inverter power supply is improved.
Foreign inverter welding machines can achieve a rated welding current of 300A, a load duration rate of 60%, a full-load voltage of 60~75V, a current adjustment range of 5~300A, and a weight of 29kg.

(2) non-isolated 24V input power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

(4) non-isolated 24V input power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

(6) non-isolated 24V input power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching 24V input power supply modules play a role that cannot be ignored and are very important.
