Abstract:
A voltage booster powered by a primary electrical source for providing an adjustable voltage across the load, while a current regulator in series with the load maintains the desired current. When the voltage drop across the current regulator exceeds an upper threshold, the voltage booster's output voltage is reduced to a lower level to reduce the power dissipated by the current regulator, to improve efficiency. When the voltage drop across the current regulator is less than a lower threshold, the voltage booster output is increased to a higher level. In burst mode operation, the voltage booster output alternates between a full voltage and zero voltage, and an optional capacitor provides voltage across the resistive load during discharge. An optional diode can ensure that the capacitor discharges through the load in cases where the voltage booster output is not floating.
