3.4 DC Link Voltage Monitor—1700V

The DC link (HI side drain to LO side source) monitor output voltage is 1% accurate from 50V to 1650V. The PWM output is the ratio of the DC link voltage per 1700V. For example, with an 825V DC link voltage, the PWM output will be 50%. The following is the linear equation for the voltage monitor PWM output with a 2 kHz four-pole filter.

V_DC [V] = 340 × V_monitor
