What does a 110V input power supply look like?(3)


(DC/DC) converter
The DC/DC converter converts a fixed DC voltage into a variable DC voltage. This technology is widely used in the stepless speed change and control of trolleybuses, subway trains, and electric vehicles. Responsive performance, and at the same time receive the effect of saving power. Replacing the varistor with a DC chopper can save power by (20~30)%. The DC chopper can not only play the role of voltage regulation (switching power supply), but also can effectively suppress the harmonic current noise on the grid side.

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.

Three: Transformer components

Determine the power and temperature resistance of the Marine boost/buck voltage power supply, it is the transformer. The transformer is responsible for the completion of AC and DC, and the energy overload will saturate the machine.

Four: Electrolytic capacitors and ceramic capacitors

Electrolytic capacitors, as well as monolithic electrolytic capacitors, which use sulfuric acid as the insulating medium, which allows for greater capacity savings, are made into smaller volumes, and are marked with a + symbol, some with an a symbol. Typically used for low frequency crosslinking and bypass filtering. The disadvantage is that the loss of mesons is greater. Monolithic electrolytic capacitors are due to their special properties. The performance of the material is better than that of ordinary electrolytic capacitors, and the frequency characteristics are better, but the capacity cannot be too large, and can be used in precision circuits and timing circuits.
