Abstract

According to one or more aspects, a health sense system for a pulse width modulation (PWM) device associated with a magnetic coil is provided, and includes a health sense circuit, a health logic circuit, and a counter circuit. The health sense circuit measures one or more current measurements at a low voltage side of the pulse width modulation device. The health logic circuit determines a health bit indicative of a health score for the magnetic coil of the pulse width modulation device based on one or more of the current measurements. The counter circuit generates a feedback command for the pulse width modulation device based on the health bit.
