<p>Preferably, the power source is a DC converter regulator including an inductor (L1) and a capacitor (C1) electrically coupled to one another. An input inverter (12) converts an input DC voltage (Es) into an AC voltage having substantially no DC component and applies the AC voltage across the inductor (L1) and capacitor (C1) in a manner which causes the inductor and capacitor to resonate with one another whereby an AC voltage appears across the capacitor. An output circuit (16) converts the AC voltage appearing across the capacitor (C1) into a DC output voltage (Ep). A control circuit (18) is provided for controlling the operation of the inverter circuit in a manner which controls the magnitude of the output voltage. </p> |
