  • Variable voltage regulator for electronic accelerator in automobile
    Patent number: 6591821
    Abstract: The present invention comprises an Electronics Control Unit (ECU) power potential stabilizing circuit and an ECU reference potential stabilizing circuit. The ECU power potential stabilizing circuit eliminates noise and stabilizes voltage variation occurring when the electrical parts of automobile are activated by the power supplied through the ECU of the electronic accelerator, by impressing it to the power supply line and variable voltage supply line. The ECU reference potential stabilizing circuit eliminates the unnecessary spark noise and harmonics noise occurring on the power supply line, reference potential line and variable voltage supply line, by impressing it to the variable voltage supply line and reference potential line. It further stabilizes the voltage supplied to the ECU by compensating the voltage fluctuated due to disturbances.
