PHASE-CONTROLLED VOLTAGE REGULATOR FOR MOTOR VEHICLES AND METHOD

摘要

A phase-controlled voltage regulator of the series type, for supplying A.C. and D.C. electric loads in electronic ignition systems for internal-combustion engines. The A.C. and/or D.C. electric load is connectable in series with a single winding magneto generator via a respective electronic control switch; the voltage existing on the electric load is continuously detected and set to a supply voltage value required by the load by controlling the start time, and the time length of activation of the electronic control switch, during each half-wave of the generator voltage having a same polarity, in relation to the detected voltage on the electric load itself; no-load operating conditions for the magneto generator are maintained during the initial period of time for each half-wave, inhibiting the conduction of the electronic control switch.
