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

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.

(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;

(2) non-isolated Marine boost/buck voltage power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

input protection circuit
General module power products have built-in filters, which can meet the requirements of general power supply applications. If a more demanding power system is required, an input filter network should be added. An LC or π-type network can be used, but care should be taken to choose a smaller inductance and larger capacitance as much as possible.
In order to prevent the transient high voltage of the input power supply from damaging the power supply of the module, it is recommended that the user connect a transient absorption diode at the input end and use it with a fuse to ensure that the module is within a safe input voltage range. In order to reduce common-mode noise, Y (Cy) capacitors can be added, and a few nf high-frequency capacitors are generally selected. R is a fuse, D1 is a protection diode, and D2 is a transient absorption diode (P6KE series).

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

(4) non-isolated Marine boost/buck voltage power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

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

(6) non-isolated Marine boost/buck voltage power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching Marine boost/buck voltage power supply modules play a role that cannot be ignored and are very important.
