STORAGE DEVICE INCLUDING PROTECTION CIRCUIT FOR SECONDARY POWER SOURCE AND METHOD OF CONTROLLING SECONDARY POWER SOURCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17719560 titled 'STORAGE DEVICE INCLUDING PROTECTION CIRCUIT FOR SECONDARY POWER SOURCE AND METHOD OF CONTROLLING SECONDARY POWER SOURCE

Simplified Explanation

The patent application describes a storage device with a secondary power source, charging circuit, protection circuit, and main system. The secondary power source consists of capacitors that are charged using a charging voltage and generate an internal power supply voltage. The charging circuit generates the charging voltage from an external power supply voltage. The protection circuit monitors the capacitors for defects and blocks any defective ones. The main system operates using either the external or internal power supply voltage.

  • The storage device includes a secondary power source with capacitors that generate an internal power supply voltage.
  • A charging circuit generates the charging voltage for the capacitors from an external power supply voltage.
  • A protection circuit monitors the capacitors for defects and blocks any defective ones.
  • The main system operates using either the external or internal power supply voltage.

Potential Applications

  • This technology can be used in various electronic devices that require a reliable and efficient power supply.
  • It can be applied in portable devices such as smartphones, tablets, and laptops to enhance their power storage capabilities.
  • It can also be used in electric vehicles to improve their energy storage systems.

Problems Solved

  • The storage device solves the problem of unreliable power supply by including a secondary power source and protection circuit to monitor and block defective capacitors.
  • It addresses the issue of limited power storage capacity in electronic devices by utilizing capacitors that can be charged and generate an internal power supply voltage.

Benefits

Original Abstract Submitted

A storage device includes a secondary power source, a charging circuit, a protection circuit and a main system. The secondary power source includes a plurality of capacitors, is charged based on a charging voltage, and generates an internal power supply voltage. The charging circuit generates the charging voltage based on an external power supply voltage. The protection circuit monitors whether at least one of the plurality of capacitors is defective, and blocks at least one defective capacitor. The main system operates based on the external or internal power supply voltage. The protection circuit includes a plurality of resistors, a plurality of transistors and a control circuit. The control circuit monitors whether the at least one of the plurality of capacitors is defective using the plurality of resistors and a plurality of currents associated with the plurality of capacitors, and blocks the at least one defective capacitor using the plurality of transistors and a plurality of control signals.
