Heat sink Requirements
Figures IRPT1053 datasheet show thermal resistance heat sink required various output power levels 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 maximum losses maximum continuous operating temperature heat sink.
maximum combined losses rectifier inverter full pulse-width modulation under overload
incremental temperature rise heat sink during overload, which limited Z^^.
minimum output frequency which full overload current delivered sets peak IGBT junction temperatures.
output frequency IGBT junction temperature tends follow instantaneous fluctuations output current. Thus, peak junction temperature rise increases output frequency decreases.
Voltage Rise During Braking
motor will feed energy back link during electric braking, forcing voltage rise above level defined input line voltage. Deceleration motor must controlled appropriate control keep voltage within rated maximum value.
