INTEGRATED POWER FUNCTIONS

600V/20A low-loss 3rd generation IGBT inverter bridge for 3 phase DC-to-AC power conversion (Fig. 2)

Application Motor Ratings : Power : 1.5kW, sinusoidal, PWM

Frequency=5kHz

100 load current : 8.0A (rms)*

150 load current : 12.0A (rms)*, 1 minute.

INTEGRATED DRIVE, PROTECTION AND SYSTEM CONTROL FUNCTIONS

• For upper-leg IGBTS :Drive circuit, High voltage isolated high-speed level shifting, Control circuit under-voltage (UV) protection.

Note : Bootstrap supply scheme can be applied (Fig. 2).

• For lower-leg IGBTS : Drive circuit, Control curcuit under-voltage protection (UV), Short circuit protection (SC). (Fig. 3)

• Fault signaling : Corresponding to a SC fault (Low-side IGBT) or a UV fault (Low-side supply).

• Input interface : 5V line CMOS/TTL compatible, Schmitt Trigger receiver circuit.

APPLICATION

AC100V~200V three-phase inverter drive for small power (1.5 kW) motor control.
