High-voltage inverter

High-voltage inverter refers to high-power inverter with input voltage of 3KV or above. The main voltage grades are high-voltage and high-power inverters with voltage levels of 3000V, 3300V, 6000V, 6600V, 10000V, etc. The high-voltage inverter is mainly imported, China There are already high-voltage inverter manufacturers, and we can use domestic high-voltage inverters in the future. It is much more convenient to save energy for high-voltage motors in large enterprises. High-voltage inverters are divided into high-low-high; low-high; high-high. The high-low-high mode high-voltage inverter is to reduce the voltage of the high-voltage power supply with a low-voltage inverter, and then use a step-up transformer to raise the voltage to the voltage we use and supply it to the high-voltage motor. Generally, the high, low and high modes are used in low-power high-voltage motors for energy-saving conversion. The low-high mode high-voltage inverter is controlled by a low-voltage inverter, and the voltage is raised to the motor using the step-up transformer. The low-high mode is also used in low-power high-voltage motors for energy-saving conversion. The high-high mode high-voltage inverter is directly connected with multiple modules of the inverter, and directly uses the high-voltage power supply to directly output the high voltage for use by the high-voltage motor. The high-level mode is mainly used in high-power high-voltage motors for energy-saving conversion. High-voltage inverters mainly include Japan Fuji high-voltage inverter, Japan Mitsubishi high-voltage inverter, Japan Toshiba high-voltage inverter, Sweden ABB high-voltage inverter, Germany Siemens high-voltage inverter, American Robin Kang high-voltage inverter, Heyi high-voltage inverter, and Dehuafu high-voltage inverters, etc.
