EXTENDING HOLD-UP TIME OF A POWER SUPPLY UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240201761 titled 'EXTENDING HOLD-UP TIME OF A POWER SUPPLY UNIT
The patent application describes a power supply unit (PSU) with a primary side containing a buck capacitor and a power factor correction (PFC) unit, and a secondary side with a super capacitor and a converter.
- The PFC unit charges the buck capacitor and super capacitor based on their state of charge (SOC) when receiving energy from a source.
- An intermediate heat sink (IHS) is connected to the PSU for energy transfer.
- In a second state, when the PFC unit stops receiving energy, the buck capacitor discharges to provide energy to the IHS.
- After the buck capacitor is fully discharged, the super capacitor discharges to provide energy to the IHS.
Potential Applications: - Energy storage systems - Uninterruptible power supplies - Renewable energy systems
Problems Solved: - Efficient energy management - Reliable power supply backup
Benefits: - Enhanced energy storage capabilities - Improved power supply reliability
Commercial Applications: Title: "Advanced Energy Storage Solutions for Power Supplies" This technology can be used in various industries such as telecommunications, data centers, and industrial automation for reliable power backup solutions.
Questions about the technology: 1. How does the super capacitor enhance the energy storage capacity of the PSU? 2. What are the advantages of using a buck capacitor in the primary side of the PSU?
Original Abstract Submitted
a psu including a primary side, including: a buck capacitor; and a pfc in electrical communication with the buck capacitor; a secondary side, including: a super capacitor; and a converter in electrical communication with an output of the primary side and in electrical communication with the super capacitor, wherein in a first state, the pfc receives energy from a source of energy, and in response: provides the energy to i) charge the buck capacitor based on a soc of the buck capacitor, ii) charge the super capacitor based on a second soc of the super capacitor; and iii) an ihs coupled to the psu, wherein in a second state, the pfc ceases to receive energy from the source of energy and in response: the buck capacitor discharges to provide energy to the ihs; after the buck capacitor is completely discharged, the super capacitor discharges to provide energy to the ihs.
