3. Functional characteristics

1) Soft switching technology

The charging module is the third generation of intelligent high-frequency switching charging module developed by our company. It adopts phase-shifted full bridge zero voltage pulse width control soft switching technology. The switch tube is zero voltage and zero current switching, without voltage and current overshoots or spikes, and has ideal soft switching characteristics. Compared to hard switching, the switching loss of the soft switching charging module is reduced by 40%, which brings obvious advantages to the charging module:

① The overall efficiency is improved, which greatly reduces the temperature rise of the charging module under the same working environment.

② Due to the absence of voltage and current overshoots or spikes, the electrical stress borne by power switching devices is small, and the reliability of power switching devices is improved.

③ Due to the reduction of the voltage change rate (dv/dt) and the current change rate (di/dt), the electromagnetic interference of the charging module is significantly reduced, and the power consumption is improved

Magnetic compatibility.

2) Intelligent module

The charging module has a built-in CPU, which coordinates the operation and protection of the management module, and accepts the control of the upper computer through electrically isolated digital communication. Its advantages include:

① The digital communication interface equipped with photoelectric isolation has electrical isolation capability and can withstand external 2000V voltage shocks.

② The instructions received by the module are digital signals, and corresponding operations can only be performed when instructions that comply with the communication protocol are received. Any illegal instructions caused by interference will not be received, which will not cause the module to malfunction.

③ When a module fails, the faulty module automatically exits without affecting the normal operation of the system.

④ The intelligent module can monitor the operation of the centralized monitor. When the centralized monitor fails, each charging module can be manually controlled to achieve voltage and current settings.

⑤ The monitoring of intelligent modules adopts a decentralized control method.
