| Patent Number: |

| Title: |
High Frequency AC Voltage Control |
| Abstract: |
This voltage control apparatus produces distortionless, stabilized
alternating output voltage subject to distortion. The apparatus comprises
a wave form reshaping circuit connected to the voltage output for
energizing a load, and an internal reference voltage generator amplitude
stabilized and synchronized with the input voltage. An error detector
generates error pulses which are applied to a controller to generate
control pulses. The control pulses are combined with the amplified
reshaped input voltage to produce the stabilized, distortionless voltage
output. An overcurrent sensor applies signals to the controller to cut off
the voltage output when the load draws excessive current. The reference
voltage generator can be adjustable to vary the amplitude of the
alternating voltage output.
