不同种类逆变器的区别
逆变器可以分为电压源型逆变器和（current source inverters，CSI）电流源型逆变器（voltage source inverters，VSI）两种，电压源型一般用作离网逆变器，电流源型一般用作并网逆变器。
下面就来介绍CSI和VSI两种逆变器的区别。
| 项目 | CSI | VSI |
|---|---|---|
| 反馈量不同1 | current source inverters are fed with constant current | voltage source inverters are fed with constant voltage |
| 输出量不同1 | the output of a CSI drive is adjustable, three-phase AC current, | while a VSI drive produces three-phase AC voltage with adjustable magnitude and frequency. |
| 储能形式不同1 | CSI drives use inductive energy storage—that is, they use inductors in their DC link to store DC energy and regulate current ripple between the converter and the inverter. | Conversely, VSI drives use capacitive storage, with capacitors in their DC link, which both stores and smooths the DC voltage for the inverter. |
| 使用的开关器件类型不同1 | Modern CSI drives typically use gate turn-off thyristors (GTOs) or symmetrical gate commutated thyristors (SGCTs). | VSI drives commonly use insulated gate bipolar transistors (IGBTs) |
| 控制调整的东西不同1 | 改变PWM调整频率 | 改变PWM调整电压和频率 |
| 集成性1 | CSI的输入和输出侧包括滤波器，因此通常为非集成的 | VSI驱动器具有较少的组件，通常作为集成设计提供，与非集成CSI设计相比，其尺寸更小。 |
| 价格22 | 昂贵，因为大电感和电容 | 相比便宜 |
| 潮流反转[^4] | 改变电流更不容易 | 容易 |
