7 / 15 page SKYPER™ 32 - Technical Explanations 7 / 15 2005-06-03 – Rev04 © by SEMIKRON characteristic or hiccup-mode can create problems if no sufficient over current margin is available. The voltage has to rise continuously and without any plateau formation as shown in the following diagram. Rising slope of the power supply voltage If the power supply is able to provide a higher current, a peak current will flow in the first instant to charge up the input capacitances on the driver. Its peak current value will be limited by the power supply and the effective impedances (e.g. distribution lines), only. It is recommended to avoid the paralleling of several customer side power supply units. Their different set current limitations may lead to dips in the supply voltage. The driver is ready for operation typically 150ms after turning on the supply voltage. The driver error signal PRIM_nERROR_OUT is operational after this time. Without any error present, the error signal will be reset. To assure a high level of system safety the TOP and BOT signal inputs should stay in a defined state (OFF state, LOW) during driver turn-on time. Only after the end of the power-on-reset, IGBT switching operation shall be permitted. Under Voltage Protection of driver power supply (UVP) 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_nERROR_OUT changes to the HIGH state. |
