What does a isolated module power supply look like?(3)


The core of the Marine boost power supply is the IC, just like the brain of the Marine boost power supply, the quality of the IC directly affects various parameters of the Marine boost power supply.

Three: Transformer components

The high-voltage DC power supply for electrostatic precipitator has been developed in China. The commercial power is rectified into DC, and the full-bridge zero-current switch series resonant inverter circuit is used to invert the DC voltage to a high-frequency voltage, which is then boosted by a high-frequency transformer, and finally rectified. for DC high voltage. Under the condition of resistive load, the output DC voltage reaches 55kV, the current reaches 15mA, and the operating frequency is 25.6kHz.

Determine the power and temperature resistance of the Marine boost 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.
