What does a DCDC converter look like?(3)

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.

Ring current backup
The ring current generator is mainly used in the telephone exchange exchange to provide ringing to the telephone users, and is generally used in a biased state. Bias can be divided into positive bias and negative bias. In order to improve the reliability of the ring current system, the ring current needs to be backed up. Installation and maintenance of module power supply
Since the types, series and specifications of the modular power supplies produced by various companies are difficult to count, their functional characteristics and physical characteristics are not the same, so they are also different in installation, use and maintenance, but the following aspects should be paid attention to

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.
