170A35V Air Cooling IGBT Power Supply for Sewage Treatment
With increasingly heavier water pollution, the sewage treatment has become the focus of global attention. In the past ten years, the booming field of sewage treatment is showing a very broad application prospects.
There are two kinds of DC power supply system for sewage treatmen: linear power supply and switching power supply. The traditional linear power supply has many defects in practical application. For example, the linear power supply can only be used for reducing voltage, and the input and output need to be separated, the design becomes more loaded. Its biggest drawback is that the power consumption is too large, the efficiency of the power system is relatively low.
Because of its high efficiency, small size and light weight, switching power supply has become the first choice of modern electrical equipment.
