Mainly divided into two categories: one is sine wave inverter and the other is square wave inverter. The sine wave inverter outputs sine wave alternating current that is the same as or even better than the power grid we use every day because it does not have electromagnetic pollution in the power grid. The square wave inverter outputs poor quality square wave alternating current, whose positive maximum value to negative maximum value occurs almost at the same time, causing severe instability to the load and the inverter itself.
At the same time, its load capacity difference is only -% of the rated load and cannot carry inductive loads. If the load is too large, the third harmonic component contained in the square wave current will increase the capacitive current flowing into the load and seriously damage the power supply filter capacitor of the load. In response to the above shortcomings, quasi-sine waves (or improved sine waves, modified sine waves, simulated sine waves, etc.) have emerged. The output waveform of the inverter has a time interval from the positive maximum value to the negative maximum value. The use effect is The improved but quasi-sinusoidal waveform is still composed of polygonal lines and belongs to the square wave category with poor continuity.
In summary, sine wave inverter provides high-quality AC power and can drive any kind of load, but the technical requirements and cost are high. The quasi-sine wave inverter can meet most of our electricity needs, has high efficiency, low noise and moderate price, so it has become a mainstream product in the market. The square wave inverter uses a simple multivibrator, and its technology is at the level of the era and will gradually disappear from the market.
According to different power generation sources, inverters are divided into coal power inverters, solar power inverters, wind power inverters, and nuclear power inverters. According to different uses, they are divided into independent control inverters and grid-connected inverters. In the world, the efficiency of solar inverters in Europe and the United States is higher. The European standard is .%, but the price is relatively expensive. The efficiency of other domestic inverters is below %, but the price is much cheaper than imports. In addition to the power waveform, it is also very important to choose the efficiency of the inverter. The higher the efficiency, the less power is wasted on the inverter and more power is used for electrical appliances. This is especially important when you use a low-power system. obvious.
Multiple series inverters have many advantages when applied to electric vehicles. The types of output voltage vectors in the series structure are greatly increased, which enhances the flexibility of control, improves the accuracy of control, and reduces the fluctuation of the motor neutral point voltage. The inverter's bypass feature increases the flexibility of charging and regenerative braking control.
With people's increasing concern about the urban environment, the development of electric vehicles has received a rare opportunity. In urban transportation, electric buses have become a priority development target due to their large carrying capacity and high comprehensive benefits. Most electric buses use three-phase AC motors. Due to the high power of the motor, the components in the three-phase inverter need to withstand high voltage and large current stress. The high d/d also causes serious electromagnetic radiation and requires good heat dissipation.
The high-power inverter that adopts a multiple series structure reduces the voltage stress endured by a single device, lowers the requirements for the device, lowers the d/d value, reduces the heat generated by the electromagnetic radiation device, and also greatly reduces the output voltage. The more flat types, the better the control performance.
