Jordan the switching frequency of the AC-DC switching power supply module?(1)
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.
What is the operating frequency of Jordan the AC-DC switching Marine boost/buck voltage power supply module? What factors need to be considered when choosing an AC-DC switching Marine boost/buck voltage power supply module? Are these questions the focus of your circuit design? The following are several elements for selecting the operating frequency.
Jordan Choosing the switching frequency of the Marine boost/buck voltage power supply does not mean choosing the switching frequency of the Marine boost/buck voltage power supply with a good switching frequency, but the choice is suitable for your own use. Most of the current market is like this. The frequency of the AC-DC switching Marine boost/buck voltage power supply module is between 50K and 135K, and this frequency range can meet most applications. Let's discuss it. Some of the problems that AC-DC encounters when choosing switching frequency:
