Abstract

The primary winding 65a of a ferroresonant transformer 65 is driven from power source 35, which comprises line frequency triggered oscillator 45 and squaring limiter 37, 38. The secondary windings 65b, 65c of the transformer are wound around saturable core portion 165b, and resonance at line frequency is achieved by self capacitance 665 or a discrete capacitor 91. The secondary resonant currents saturate the core during each half cycle, and the induced voltages in both secondaries are consequently regulated. One voltage is arranged to be the EHT voltage U, and the other, the sweep voltage V. The invention avoids the need for separate B<+> and EHT regulators, or a series stabiliser resistor or sensing beam current changes.
