Abstract

1,040,244. Automatic control of waveforms. LICENTIA PATENT VERWALTUNGS-G.m.b.H. April 5, 1963 [April 5, 1962], No. 13624/63. Addition to 1, 036, 464. Heading G3R. [Also in Division H2] An inverter 1 of the kind disclosed in the parent Specification delivers at a high frequency alternate positive and negative pulses whose width is modulated by a low frequency signal applied at 8. The inverter output is filtered at 4, 5 and the low frequency component fed to a load 3. A voltage ui proportional to the load current is compared with a sinusoidal reference voltage u s to provide the control signal at 8. In this way the load current is made to follow the waveform as well as the magnitude of the reference.
