6 FAQs about [Energy storage power supply ac has no output]
What happens if an AC-DC power supply is interrupted?
An ac-dc power supply’s input voltage can be interrupted during circumstances such as a brown out condition or a brief power failure. When this happens, the dc output will only remain within regulation for a short period of time. The time period is specified on the power supply datasheet as the hold-up time.
What if a power supply is uncharged?
One other major concern is the over-current of the power supply during initial turn-on. An uncharged output capacitance would appear to the power supply control circuit as a dead short across the output. The power supply would most likely fail to establish a 12-V output when initially turned on. 3.
What happens if a power supply has an uncharged output capacitance?
An uncharged output capacitance would appear to the power supply control circuit as a dead short across the output. The power supply would most likely fail to establish a 12-V output when initially turned on. 3. A customized power supply with a larger high-voltage bus capacitor (C1).
Can a power module boost supply hold-up time?
A power-module-based approach could also employ a non-isolated ac-dc 360-Vdc-output converter and a high-voltage input isolated dc-dc 12-V-output converter. This approach again would require a custom board design with engineering and safety certification charges. The pros and cons of typical approaches aimed at boosting supply hold-up time.
How to extend power supply hold-up time?
There are various methods to extend power supply hold-up time, each with advantages and disadvantages. The amount of energy E stored in a capacitor C is E = ½ CV 2. To increase that energy storage and hence the hold-up time, either the amount of capacitance or the voltage on the capacitor must rise.
What if a power supply had a hold-up time of 20 msec?
If the power supply to be modified had a hold-up time of 20 msec, increasing it to 200 msec would require adding the equivalent of nine more C1 capacitors. As C1 typically occupies 5 to 6% of the internal space of a power supply, this strategy would increase the size of the power supply by around 50% for the same product height.
