High-voltage switch power supply products are all the rage right now, but one converter stands out, the DC-DC 12v to 5v. Modern examples of high-voltage switching power supply products are based on SMPS technology, converting low-frequency, low-voltage input to a high-voltage one. The whole idea behind SMPS is to convert with high-frequency switches (MOSFETs) and transformers.
High-voltage power supply transformers are tricky. They
rectify and filter DC bus voltages (gained by rectification of the main input,
etc.). These switches generally operate at 2kHz, controlled by the duty-ratio
(so that power transfer is regulated). Like we said, it’s tricky!
One converter works its way into the mix time and time
again: the DC-DC
converter 12v to 5v.
In the case of the transformer, it’s got a prime source of galvanic isolation.
As the stepped-up voltages are rectified, multiplied, and filtered, the HF
transformer springs into action.
Let’s be honest here. The control circuitry is complex when
implemented in this way. The power supply is regulated, nonetheless, by user
demand. The circuit includes a fail-safe option so that nothing bad happens.
High-voltage power supply is complex in nature. It’s a power
conversion circuit that converts a lower-voltage potential to a higher one.
Remember that the idea of high voltage isn’t based on a number – it’s more of a
concept. To learn more: www.hvmtech.com.
