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

power source is realized through the power transfer switch.
Modern UPS generally adopts pulse width modulation technology and modern power electronic devices such as power MOSFET, IGBT, etc., the noise of power supply can be reduced, and the efficiency and reliability can be improved. The introduction of microprocessor software and hardware technology can realize intelligent management of UPS, remote maintenance and remote diagnosis.
The maximum capacity of the online UPS can be made to 600kVA. The development of ultra-small UPS is also very rapid, and there are already 0.5kVA, lVA, 2kVA, 3kVA and other products of various specifications.

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.
