Hra2460d-2w high voltage power supply high voltage module - high voltage - high precision hra2460d-2w

DC/DC Conversion is to convert a variable DC voltage into a fixed and stable DC voltage , Also known as DC chopper . The chopper works in two ways , One is pulse width modulation Ts unchanged , change ton( Universal ), Second, frequency modulation

(1)Buck circuit —— Step down chopper , Its output average voltage U0 Less than the input voltage Ui, Same polarity .

(2)Boost circuit —— Boost chopper , Its output average voltage U0 Greater than the input voltage Ui, Same polarity .

(3)Buck-Boost circuit —— Step down or boost chopper , Its output average voltage U0 Greater than or less than the input voltage Ui, Opposite polarity , Inductive transmission .

(4)Cuk circuit —— Step down or boost chopper , Its output average voltage U0 Greater than or less than the input voltage Ui, Opposite polarity , Capacitive transmission . also Sepic、Zeta circuit .

The above is non isolated DC-DC Converter circuit , Isolated type DC-DC The converter has a forward circuit 、 Flyback circuit 、 Half bridge circuit 、 Full bridge circuit 、 push-pull circuit .

3、 ... and 、 Advantages of using power module

At present, different suppliers launch a variety of different power modules in the market , The input voltage of different products 、 Output power 、 The function and topology are different . Using power module can save development time , So that products can be launched to the market faster , Therefore, the power module is superior to the integrated solution . The power module also has the following advantages ：

Each module can be the first mock exam. , To ensure its high reliability , This includes energizing test , In order to eliminate substandard products . By contrast , Integrated solutions are harder to test , Because the whole power supply system is closely connected with other functional systems on the circuit .

Different suppliers can design modules of the same size according to existing technical standards , Provide a variety of different options for engineers designing power supplies .

The first mock exam is carried out in accordance with the standard performance requirements. , It helps to reduce the risk of adopting new technologies .

If an integrated solution is adopted , Once there is a problem with the power supply system , The whole motherboard needs to be replaced ; If modular design is adopted , Just replace the problem module , This helps to save costs and development time .
