Abstract
The present invention is a method and system for actively limiting transient voltages across a voltage bus. Circuitry coupled to a bus may adjust the voltage level of a bus to a voltage within a desired range when transient voltages cause the voltage level on the bus to fall outside of a desired range. Circuitry of the present invention may include active elements that may adjust a voltage level of a bus in a rapid fashion. Additionally, use of the circuitry of the present invention reduces the cost and design limitations associated with stabilizing buses by solely using multiple low ESR/ESL capacitors.
