8 / 16 page SKYPER™ 32PRO - Technical Explanations 8 / 16 2005-06-03 – Rev02 © by SEMIKRON Under Voltage Protection (UVP) primary The internally detected supply voltage of the driver has an under voltage protection. The table below gives an overview of the trip level. Supply voltage UVP level Regulated +15V ±4% 13,5V If the internally detected supply voltage of the driver falls below this level, the IGBTs will be switched off (IGBT driving signals set to LOW). The input side switching signals of the driver will be ignored. The error memory will be set, and the output PRIM_HOLD_OUT changes to the HIGH state. Under Voltage Protection secondary This function monitors the rectified voltage on the secondary side. If the voltage drops, the IGBTs will be switched off (IGBT driving signal set to LOW). The input side switching signals of the driver will be ignored. No failure message will be generated. Output voltage UVP level Regulated +15V 12V Input Signals The signal transfer to each IGBT is made with pulse transformers, used for switching on and switching off of the IGBT. The inputs have a Schmitt Trigger characteristic and a positive / active high logic (input HIGH = IGBT on; input LOW = IGBT off). It is mandatory to use circuits which switch active to +15V and 0V. Pull up and open collector output stages must not be used for TOP / BOT control signals. It is recommended choosing the line drivers according to the demanded length of the signal wires. TOP / BOT Input A capacitor is connected to the input to obtain high noise immunity. This capacitor can cause for current limited line drivers a little delay of few ns, which can be neglected. The capacitors have to be placed as close as possible to the driver interface. Please note: It is not permitted to apply switching pulses shorter than 1µs. |
