Figure 7. Charging Path from 15V Supply to DC Bus when DC Bus is off
• Each IGBT is protected against desaturation.
• D2 is the desaturation sense diode for the high-side IGBT
• D3 is the desaturation sense diode for the low-side IGBT
• When the DC bus voltage is not applied or below 15V, there is a charging path from the
15V supply to the DC bus through D2 and D3 and the corresponding pull up 100K Ohm
resistor. The charging current is 0.15mA per IGBT. Total charging current is about
1.5mA.
• Do not apply PWM signal if the DC bus voltage is below 20V.
