MC3PHAC-VDW
3-Phase AC Motor Controller
OverviewThe MC3PHAC is a high-performance monolithic intelligent motor controller
designed specifically to meet the requirements for low-cost, variable-speed,
3-phase ac motor control systems. The device is adaptable and configurable,
based on its environment. It contains all of the active functions required to
implement the control portion of an open loop, 3-phase ac motor drive.
One of the unique aspects of this device is that although it is adaptable and
configurable based on its environment, it does not require any software
development. This makes the MC3PHAC a perfect fit for customer applications
requiring ac motor control but with limited or no software resources available.
The device features are: Volts-per-Hertz speed control Digital signal processing (DSP) filtering to enhance speed stability 32-bit calculations for high-precision operation Internet enabled No user software development required for operation 6-output pulse-width modulator (PWM) 3-phase waveform generation 4-channel analog-to-digital converter (ADC) User configurable for standalone or hosted operation Dynamic bus ripple cancellation Selectable PWM polarity and frequency Selectable 50/60 Hz base frequency Phase-lock loop (PLL) based system oscillator Serial communications interface (SCI) Low-power supply voltage detection circuit
