    • PURPOSE: A starting system and method for a micro-turbine is provided to reduce switching losses and to obtain simplified control technology of a power control circuit. CONSTITUTION: A method for starting a turbine(12) coupled to an electric machine(14) for supplying power to a load(16) through a DC bus(24), comprises the steps of: gradually increasing a voltage level of the DC bus; converting DC power from the DC bus to AC power such that the frequency of the AC power increases in proportion to the gradually increasing voltage level of the DC bus; and applying the AC power to drive electric machine so that the electric machine drives the turbine at a starting speed. The method for starting the turbine further comprises after the startup phase, the steps of: driving the electric machine with the turbine to generate AC power; converting the generated AC power from the electric machine to DC power applied to the DC bus; converting the DC power from the DC bus to load-driving AC power; and supplying the load-driving AC power to the load.
    • 目的:提供微型涡轮机的启动系统和方法,以减少开关损耗并获得功率控制电路的简化控制技术。 构成:用于启动耦合到电机(14)的用于通过DC总线(24)向负载(16)供电的涡轮机(12)的方法包括以下步骤:逐渐增加DC总线的电压电平 ; 将直流电源从直流总线转换成交流电源,使得交流电源的频率与直流母线的逐渐增加的电压电平成比例地增加; 并施加交流电力来驱动电机,使电机以启动速度驱动涡轮机。 起动涡轮机的方法还包括在起动阶段之后的步骤:用涡轮机驱动电机以产生交流电; 将从电机产生的AC电力转换为施加到DC总线的DC电力; 将直流电源从直流总线转换为负载驱动交流电; 并向负载提供负载驱动AC电力。
