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. INTEGRATED DRIVE, PROTECTION AND SYSTEM CONTROL FUNCTIONS: • For P-Side IGBTs : Drive circuit, High voltage isolated high-speed level shifting, 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 (FO) signaling circuit, 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 phase current (3φ). • Input Interface : 5V CMOS/TTL compatible, Schmitt trigger input, and Arm-Shoot-Through interlock protection. APPLICATION Acoustic noise-less 3.7kW/AC200V class 3 phase inverter and other motor control applications.
