技术领域technical field

背景技术Background technique
图6所示的电磁弹射器是一种典型的脉冲动力耦合系统，主要由弹射直线电动机、电能存储装置和功率变换器构成，它将利用由直线电机产生的行进电磁力推动飞机达到起飞速度，其主要应用是大载荷的短程加速，运行工况的显著特点就是时间短，功率大。电能存储技术是电磁弹射系统关键技术之一，通常采用超级电容器、蓄电池、惯性飞轮等作为能量存储装置，其共同特点是存储能量有限，输出功率有限，区别于无限大电网供电，属于有限能源系统，有限能源系统典型的运行特点是充电时间长、放电时间短、输出峰值功率大，因而要求其具有高的功率密度；同时，弹射系统需要全功率的半导体功率变换器将直流电能转换为交流电能来驱动弹射直线电动机，因此功率变换器的体积大、成本高、可靠性差，同时也增加了能量传递过程中的损耗，而且，大容量的功率变换器输出电流谐波分量大，使得电动机的效率低、振动大、噪声高。The electromagnetic catapult shown in Figure 6 is a typical pulse power coupling system, which is mainly composed of an ejection linear motor, an electric energy storage device, and a power converter. It will use the traveling electromagnetic force generated by the linear motor to push the aircraft to take-off speed. Its main application is the short-distance acceleration of large loads. The remarkable characteristics of the operating conditions are short time and high power. Electric energy storage technology is one of the key technologies of the electromagnetic ejection system. Supercapacitors, batteries, inertial flywheels, etc. are usually used as energy storage devices. Their common characteristics are limited energy storage and limited output power, which is different from the infinite grid power supply and belongs to the limited energy system. , the typical operating characteristics of limited energy systems are long charging time, short discharging time, and large output peak power, so it is required to have high power density; at the same time, the ejection system requires a full-power semiconductor power converter to convert DC power into AC power. to drive the ejection linear motor, so the power converter is large in size, high in cost and poor in reliability, and also increases the loss in the process of energy transfer. Moreover, the output current harmonic component of the large-capacity power converter is large, making the efficiency of the motor Low, large vibration, high noise.

工作原理：working principle:
激磁逆变器将中等功率电力系统或电能存储装置中的电能转换为频率可变的交流电能驱动能量输入机电能量变换器1，使其转子带动惯性飞轮加速旋转到额定转速，由于能量输入机电能量变换器1气隙旋转磁场会“切割”其电功率传递绕组，在绕组内产生感应电动势；通过闭合开关单元3，使能量输入机电能量变换器1与动力输出机电能量变换器2的电功率传递绕组连接在一起，能量输入机电能量变换器1发出交流电能，输出给动力输出机电能量变换器2，在动力输出机电能量变换器2产生旋转磁场，旋转磁场“切割”实心铁磁性转子或笼型转子，在转子中感应电流，电流与旋转磁场相互作用，产生电磁转矩，驱动转子加速旋转，从而实现从系统输入电能到输出机械能的转换，而且系统输入为中小功率，而动力输出为峰值高的脉冲功率，输出与输入功率之比为数倍以上。The excitation inverter converts the electric energy in the medium-power power system or electric energy storage device into variable-frequency AC electric energy, which drives the energy input to the electromechanical energy converter 1, so that its rotor drives the inertial flywheel to accelerate and rotate to the rated speed. Due to the energy input electromechanical energy The air-gap rotating magnetic field of converter 1 will "cut" its electric power transmission winding, and induce electromotive force in the winding; by closing the switch unit 3, the energy input electromechanical energy converter 1 is connected to the electric power transmission winding of the power output electromechanical energy converter 2 Together, the energy input electromechanical energy converter 1 generates AC power, which is output to the power output electromechanical energy converter 2, where a rotating magnetic field is generated in the power output electromechanical energy converter 2, and the rotating magnetic field "cuts" the solid ferromagnetic rotor or cage rotor, The current is induced in the rotor, and the current interacts with the rotating magnetic field to generate electromagnetic torque, which drives the rotor to accelerate the rotation, thereby realizing the conversion from the system input electrical energy to the output mechanical energy, and the system input is small and medium power, while the power output is a pulse with a high peak value Power, the ratio of output to input power is more than several times.
