Trans-Inductor Voltage Regulator For High Bandwidth Power Delivery - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240120847 titled 'Trans-Inductor Voltage Regulator For High Bandwidth Power Delivery

Simplified Explanation

The abstract describes a voltage regulator with multiple main stages and at least one accelerated voltage regulator (AVR) bridge. The main stages regulate DC output voltage in response to low frequency current transients, while the AVR bridges respond to high frequency current transients without regulating the DC output voltage. The AVR bridge frequency response range can overlap with the main stage frequency response range.

• The voltage regulator has multiple main stages and at least one accelerated voltage regulator (AVR) bridge.
• Main stages regulate DC output voltage in response to low frequency current transients.
• AVR bridges respond to high frequency current transients without regulating the DC output voltage.
• AVR bridge frequency response range can overlap with the main stage frequency response range.
• The lowest frequency to which the AVR bridges respond may be set lower than the highest frequency to which the main stages respond.

Potential Applications

The technology could be applied in power supply units for electronic devices, ensuring stable and efficient voltage regulation across a wide range of frequencies.

Problems Solved

This technology addresses the challenge of effectively regulating both low and high frequency current transients in a voltage regulator, improving overall performance and reliability.

Benefits

The benefits of this technology include enhanced voltage regulation, improved response to current transients, and increased efficiency in power supply units.

Potential Commercial Applications

One potential commercial application of this technology could be in the development of advanced power supply units for consumer electronics, telecommunications equipment, and industrial machinery.

Possible Prior Art

One possible prior art could be the use of separate voltage regulators for low and high frequency current transients in power supply units, but the integration of multiple main stages and accelerated voltage regulator bridges in a single system may be a novel approach.

Unanswered Questions

How does the integration of multiple main stages and AVR bridges impact the overall size and cost of the voltage regulator system?

The abstract does not provide information on the potential impact of integrating multiple main stages and AVR bridges on the size and cost of the voltage regulator system. This could be a crucial factor for manufacturers and consumers to consider when implementing this technology.

Are there any limitations to the frequency response ranges of the AVR bridges and main stages in terms of efficiency and performance?

The abstract does not mention any limitations to the frequency response ranges of the AVR bridges and main stages. Understanding the potential limitations of these components could help in optimizing the design and performance of the voltage regulator system.

Original Abstract Submitted

a voltage regulator having a multiple of main stages and at least one accelerated voltage regulator (avr) bridge is provided. the main stages may respond to low frequency current transients and provide dc output voltage regulation. the avr bridges are switched much faster than the main stages and respond to high frequency current transients without regulating the dc output voltage. the avr bridge frequency response range can overlap with the main stage frequency response range, and the lowest frequency to which the avr bridges respond may be set lower than the highest frequency to which the main stages respond.
