METHOD AND APPARATUS FOR CONTROLLING PULSE WIDTH MODULATION DEVICE

摘要

A pulse width modulation sensor system is provided in which a sensor (116) c an be decoupled from the circuit so as to avoid transients. A switching circuit (120) can be coupled between the sensor and the pulse width modulation inverter switching circuit (112) and operated before a switching transition of the inverter switching circuit occurs. However, the sensing period is preferably implemented for a substantial portion of the period so as to be more responsive than conventional sample and hold techniques.
