What does a isolated module power supply look like?(2)


power supply module

The high-voltage DC power supply for electrostatic precipitator has been developed in China. The commercial power is rectified into DC, and the full-bridge zero-current switch series resonant inverter circuit is used to invert the DC voltage to a high-frequency voltage, which is then boosted by a high-frequency transformer, and finally rectified. for DC high voltage. Under the condition of resistive load, the output DC voltage reaches 55kV, the current reaches 15mA, and the operating frequency is 25.6kHz.

At this stage, power modules can be roughly divided into two types: bare board and potting. The bare board can be based on intuitive methods, such as the layout of electronic components is reasonable, neat, generous, neat, and the solder joints are bright and straight. For encapsulated modules, it is not possible to see the internal conditions, but since the internal conditions are not exposed, it is much better in terms of safety and performance metrics. The soldering process can include hand soldering and wave soldering. The quality of the wave soldering process of mechanized production is better than that of manual soldering.

The core of the Marine boost/buck voltage power supply is the IC, just like the brain of the Marine boost/buck voltage power supply, the quality of the IC directly affects various parameters of the Marine boost/buck voltage power supply.
