INTEGRATED FUNCTIONS AND FEATURES • 3-Phase IGBT inverter bridge configured by the latest 3rd. generation IGBT and diode technologies. • Circuit for dynamic braking of motor regenerative energy. • Inverter output current capability Io (Note 1) : INTEGRATED DRIVE, PROTECTION AND SYSTEM CONTROL FUNCTIONS: • For P-Side IGBTs : Drive circuit, High-speed photo-couplers, Short circuit protection (SC), Bootstrap circuit supply scheme (Single drive power supply ) and Under-voltage protection (UV). • For N-Side IGBTs : Drive circuit, Short-circuit protection (SC), Control supply Under voltage and Over voltage protection (OV/UV), System Over temperature protection (OT), Fault output signaling circuit (Fo), and Current-Limit warning signal output (CL). • For Brake circuit IGBT : Drive circuit. • Warning and Fault signaling : FO1 : Short circuit protection for lower-leg IGBTs and Input interlocking against spurious arm shoot-through. FO2 : N-side control supply abnormality locking (OV/UV) FO3 : System over-temperature protection (OT). CL : Warning for inverter current overload condition • For system feedback control : Analogue signal feedback reproducing actual inverter output phase current (3φ). • Input Interface : 5V CMOS/TTL compatible, Schmitt trigger input, and Arm-Shoot-Through interlock protection. APPLICATION Acoustic noise-less 0.4kW/AC400V Class 3 Phase inverter and other motor control applications.
