Functional Information
Heat Sink Requirements
Figure shows thermal resistance heat sink required various output power levels pulse-width-modulated (PWM) switching frequencies. Maximum total losses unit also shown. This data based following operating conditions: maximum continuous combined losses rectifier inverter occur full pulse-width-modulation. These losses maximum continuous operating temperature heat sink. maximum combined losses rectifier inverter full pulse-width modulation under overload increment temperature rise heat sink during overload. minimum output frequency which full load current delivered, sets peak IGBT junction temperature. frequency, IGBT junction temperature tends follow instantaneous fluctuations output current. Thus, peak junction temperature rise increases output frequency decreases.
Over-Temperature Protection
Over-temperature detected using thermistor included power module thermal sensing. protection circuit that initiates shutdown temperature exceeds level implemented. nominal resistance temperature characteristic thermistor given figure
Voltage Rise During Braking
motor will feed energy back link during regenerative braking, forcing voltage rise above level defined input voltage. Deceleration motor must controlled appropriate control keep voltage within rated maximum value. high inertial loads, very fast deceleration rates, this achieved connecting external braking resistor across controlling brake IGBT switching when voltage exceeds allowable limit.
