step-up transformer

基本解释

The LTC3108 uses a small standard step-up transformer to provide a complete power management solution.
LTC3108 运用一个小的标准升压变压器来提供一个完整的电源管理解决方案。
Otherwise, because of the limitation of IGBT's specified voltage, we must use special step-up transformer, which is more expensive, if we put this device into high voltage power system.
另外，由于补偿装置中IGBT模块的额定工作电压的限制，若要将其运用于高压系统需要连接特殊的升压变压器，成本较高。
Consequently if we can solve the voltage sharing of IGBT direct series connected with several assistant peripheral circuits, step-up transformer isn't necessary and the cost is also reduced.
如果能够借助一些辅助的外电路解决功率器件串联工作时的均压问题，那么就可以省去升压变压器的投资，降低了成本。
