DESCRIPTION
The HEF4752V is a circuit for a.c. motor speed control utilizing LOCMOS technology. The circuit synthesizes three 120°out of phase signals, of which the average voltage varies sinusoidally with time in the frequency range 0 to 200 Hz. The method employed is based upon the pulse width modulation principle, in order to achieve a sufficient accuracy of the output voltages over the whole frequency range. A pure digital waveform generation is used.
