Using Mao Zedong Thought to Improve the Efficiency of Counter-inspiration [Copy link]

Recently, in a case of 9-150V input and 12V 8A output flyback, several measures to improve efficiency were compared:

1. Further optimize the transformer and reduce RCD loss;

2. LCD clamping;

3. Active clamping;

Guess which one has the best value for money?

Is it [90-150V input]?

20-130V was mass-produced years ago, and customers further required the input lower limit to be reduced to 9V. Facts have proved that Chairman Mao was right: all difficulties are paper tigers!

Optimizing the transformer structure may be the least expensive of the three methods. Of course, it is only possible.

There should be no typos, because 90-150 input is not as challenging as 9-150 input.

9-150V input is not impossible, it is completely possible. However, such a wide range of input voltage will definitely require more expensive materials.

(I am returning to your sofa from the bench, because my quote from Chairman Mao is still under review.)

The materials are definitely more expensive. The customer needs to eat a banquet with a price of 5,000 yuan per table for the wind turbine control power supply. We definitely cannot arrange it for 1,000 yuan! There must be a few hard dishes to be worth the price. We can't feel bad about purchasing local pork, free-range chicken and farm dishes.

In addition, our most common power supplies also use electrolytic capacitors from Black King Kong and Wanyu, and we don’t even look down on Taiwan’s Capxon. This time, even solid-state capacitors are used for the output.

You can't randomly quote leaders, and you have to review them one after another, haha

Ha, I came here to see how to use Chairman Mao’s Quotations for guidance.
