1. According to the frequency of AC power output by the inverter, it can be divided into power frequency inverter, intermediate frequency inverter and high frequency inverter. The frequency of the power frequency inverter is 50~60Hz; The frequency of intermediate frequency inverter is generally 400Hz to more than 10 kHz; The frequency of high-frequency inverter is generally from more than 10 kHz to MHz.
2. According to the phase number of inverter output, it can be divided into single-phase inverter, three-phase inverter and multi-phase inverter.
3. According to the direction of the output electric energy of the inverter, it can be divided into active inverter and passive inverter. The inverter that transmits the electrical energy output by the inverter to the industrial power grid is called the active inverter; The inverter that transmits the electrical energy output by the inverter to a certain electrical load is called passive inverter.
4. According to the form of main circuit of inverter, it can be divided into single-ended inverter, push-pull inverter, half-bridge inverter and full-bridge inverter.
5. According to the type of main switch device of inverter, it can be divided into thyristor inverter, transistor inverter, field effect inverter and insulated gate bipolar transistor (IGBT) inverter. It can also be divided into two categories: "half controlled" inverter and "full controlled" inverter. The former does not have the self-closing ability, and the components will lose control after being turned on, so it is called "semi-controlled" ordinary thyristor, which belongs to this category; The latter has the self-turn-off capability, that is, the turn-on and turn-off of the non-device can be controlled by the control electrode, so it is called "fully controlled type". The power field effect transistor and insulated gate double-weight transistor (IGBT) belong to this category.
6. According to DC power supply, it can be divided into voltage source inverter (VSI) and current source inverter (CSI). In the former, the DC voltage is nearly constant and the output voltage is an alternating square wave; In the latter, the DC current is nearly constant, and the transmission current is an alternating square wave.
7. According to the waveform of inverter output voltage or current, it can be divided into sine wave output inverter and non-sinusoidal wave output inverter.
8. According to the control mode of inverter, it can be divided into frequency modulation (PFM) inverter and pulse width modulation (PWM) inverter.
9. According to the working mode of inverter switching circuit, it can be divided into resonant inverter, fixed-frequency hard-switching inverter and fixed-frequency soft-switching inverter. 10. According to the inverter commutation mode, it can be divided into load commutation inverter and self-commutation inverter.
The above are the types of inverters introduced by Xiaobian. After understanding, you can select the appropriate inverter according to your needs.
逆变器的种类很多,可按照不同的方法进行分类。下面小编就为您介绍一下逆变器的种类,跟随小编一起来看一下吧。
1、按逆变器输出交流电能的频率分,可分为工频逆变器、中频逆器和高频逆变器。工频逆变器的频率为50~60Hz的逆变器;中频逆变器的频率一般为400Hz到十几kHz;高频逆变器的频率一般为十几kHz到MHz。
2、按逆变器输出的相数分,可分为单相逆变器、三相逆变器和多相逆变器。
3、按照逆变器输出电能的去向分,可分为有源逆变器和无源逆变器。凡将逆变器输出的电能向工业电网输送的逆变器,称为有源逆变器;凡将逆变器输出的电能输向某种用电负载的逆变器称为无源逆变器。
4、按逆变器主电路的形式分,可分为单端式逆变器,推挽式逆变器、半桥式逆变器和全桥式逆变器。
5、按逆变器主开关器件的类型分,可分为晶闸管逆变器、晶体管逆变器、场效应逆变器和绝缘栅双极晶体管(IGBT)逆变器等。又可将其归纳为“半控型”逆变器和“全控制”逆变器两大类。前者,不具备自关断能力,元器件在导通后即失去控制作用,故称之为“半控型”普通晶闸管即属于这一类;后者,则具有自关断能力,即无器件的导通和关断均可由控制极加以控制,故称之为“全控型”,电力场效应晶体管和绝缘栅双权晶体管(IGBT)等均属于这一类。
6、按直流电源分,可分为电压源型逆变器(VSI)和电流源型逆变器(CSI)。前者,直流电压近于恒定,输出电压为交变方波;后者,直流电流近于恒定,输也电流为交变方波。
7、按逆变器输出电压或电流的波形分,可分为正弦波输出逆变器和非正弦波输出逆变器。
8、按逆变器控制方式分,可分为调频式(PFM)逆变器和调脉宽式(PWM)逆变器。
9、按逆变器开关电路工作方式分,可分为谐振式逆变器,定频硬开关式逆变器和定频软开关式逆变器。10、按逆变器换流方式分,可分为负载换流式逆变器和自换流式逆变器。
以上就是小编为您介绍的逆变器的种类,通过了解之后,您可以根据自己的需求,选择合适的逆变器。
