Each inverter has a DC voltage value, such as 12V, 24V, etc. It is required that the battery voltage selected must be consistent with the inverter's DC input voltage. For example, a 12V inverter must choose a 12V battery.
The output power of the inverter must be greater than the power used by the electrical appliances, especially for electrical appliances with high power at startup, such as refrigerators and air conditioners, a larger margin should be left.
Multiple series inverters are suitable for high-power electric vehicle drive systems. The use of multiple series-connected structures can reduce the risk of multiple batteries in series, reduce the switching stress of the device and reduce electromagnetic radiation. But the number of batteries required has increased by a factor of 2.
The multiple series structure output voltage vector types are greatly increased, thereby enhancing the flexibility of control and improving the accuracy of control; at the same time, the fluctuation of the neutral point voltage of the motor is reduced. In order to maintain the balance of the power of each battery, it is necessary to ensure that the discharge time of the battery is consistent during operation. By bypassing, the battery pack can be charged flexibly and the torque of regenerative braking can also be controlled.
The 300W inverter battery must be equipped with a minimum of 60AH. The battery output of 25A will not have much impact on the battery. Just like the battery of a car, the battery is generally 45-55AH and the output current is all at the time of startup. Above 60A.
The inverter converts direct current (battery, storage battery) into alternating current (usually 220V, 50Hz sine wave). It is composed of inverter bridge, control logic and filter circuit. It is widely used in air conditioners, home theaters, electric grinding wheels, electric tools, sewing machines, DVD, VCD, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. In foreign countries, because of the high popularity of automobiles, you can use inverters to connect batteries to drive electrical appliances and various tools to work when you go out to work or travel. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. More power inverter power supply should be connected to the battery through the connecting wire. Various electrical appliances can be used in the car by connecting household appliances to the output end of the power converter. The electrical appliances that can be used are: mobile phones, laptops, digital cameras, cameras, lights, electric shavers, CD players, game consoles, handheld computers, power tools, car refrigerators, and various travel, camping, and medical emergency appliances Wait.
