Abstract
Abstract A fully automatic phase controller for non-coil armature type generator includes a starting control circuit and an automatic voltage control circuit, to fully automatically control the phase according to the range of the amplitude or the forward and backward movement of a pulse train, by means of magnetic saturation using a TRIAC and a voltage stabilizer. According to the present invention, the controller is very compact and inexpensive to manufacture, which helps to provide a stable voltage while the phase is fully automatically controlled.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
231 words
An automatic phase controller for a non-coil armature-type generator, comprising: a starting control circuit, including a first capacitor electrically connected between a first stator coil and a relay, a first variable resistor connected to the first stator coil for setting a desired starting voltage, a first TRIAC switch controller comprising a first TRIAC electrically connected between said first stator coil and the control terminal of said relay and a first voltage stabilizer arranged to trigger said first TRIAC when the voltage across said first variable resistor reaches said desired starting voltage, whereby said first TRIAC opens said relay when triggered said first voltage stabilizer; and an automatic voltage control circuit, including a second variable resistor electrically connected to the output of said starting control circuit, a second TRIAC switch controller comprising a second voltage stabilizer and a second TRIAC, a second transformer electrically connected between said second TRIAC and said generator, a second capacitor arranged in parallel with said generator; and an inductive magnetic saturation regulator arranged in parallel with said generator; whereby said second TRIAC switch controller is arranged to induce a current to flow in said magnetic saturation regulator so that said magnetic saturation regulator shifts the generator output current phase a desired amount in accordance with the values of said second capacitor and said second variable resistor, said generator output current flowing only when said relay is opened.
