PWM to Voltage Output D/A Converters
-
Analog Devices’ pulse-width modulation (PWM) to voltage output D/A converters convert a PWM input to an accurate, stable, buffered voltage without the ripple, slow settling, and external passive components of discrete filter implementations. Our PWM D/A converters measure the period and pulse width of a PWM input signal and immediately update the D/A converter output with up to 12-bit accuracy and no software coding required. This family of D/A converters is available with 8-bit to 12-bit resolution, dual and quad channels, integrated references, and with high temperature operation. Applications include isolated motor control, automotive headlights or industrial lighting, and other applications that benefit from the simple control interface.

Motor Termination Units
-
Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.
