Information： | 5SHY3545L0016 desaturation detection uses IGBT itself as a current m easuring element.The diode in the schematic diagram ensures that the collector emitter voltage of IGBT is only monitored by the detection circu it during the conduction period In normal operation,the collector emitter voltage is very low(typically 1 V to 4 V).However,if a short circuit event occurs,the IGBT collector current rises to the level that drives the IGBT to exit the saturation area and enter the linear working area.This causes th e collector emitter voltage to rise rapidly.The above normal voltage level can be used to indicate that 5 SHY3545L0016 has a short circuit,while th e threshold level of desaturation jump is usually in the range of 7 V to9V.Importantly,desaturation can also indicate that the grid emitter volta ge is too low and the IGBT is not fully driven to the saturation region.Desaturation detection should be deployed carefully to prevent false trig gering.This may happen especially when the IGBT has not fully entered the saturation state,during the transition from IGBT off state to IGBT oI state.The blanking time is usually between the opening signal and the activation time of desaturation detection to avoid false detection.A cur rent source charging capacitor or RC filter is usually added to generate a short time constant in the detection mechanism to filter the filter spuriou s jump caused by noise pickup.When selecting these filter elements,it is necessary to balance the noise immunity and re sponse within IGBT short-circuit withstand time. |
