Steady-State Characteristics of Carbon-Pile Voltage Regulators

The use of a feed-back electronic control circuit permits measurement of steady-state carbon-pile regulator characteristics throughout the complete operating range. Measurements obtained using such a circuit reveal the part played by magnetic hysteresis in determining regulator performance. The effects of ambient temperature and carbon-pile power dissipation have also been studied and the latter is found to be of greater relative importance. Magnetic hysteresis is found to have the beneficial effect of permitting good regulation of large disturbances, yet tending to stabilize the regulated system in the steady state.
