  • Asymmetrical power supply
    Patent number: 5751603
    Abstract: An active asymmetrical power supply comprising a power supply, a load sensor and a voltage reference selection circuit. The load current sensor preferably, is coupled between the power supply and a load to provide the voltage reference selection circuit information regarding the amount of load current being applied to the load. The load current can be measured as a function of a voltage drop across the load current sensor. The voltage reference selection circuit actively offsets an operating voltage (or DC set voltage) in response to the amount of load current being applied to the load.
