摘要
400 Hz交流型回馈式负载用于400 Hz中频电源类产品的带载性能测试和连续运行考核。可将被测试电源输出的400 Hz频率的电能以50 Hz正弦波的形式馈入电网,该负载具输入电流功率因数可调的特点,可取代传统的电阻、电感和电容负载,是一种"绿色"节能型负载。
The 400 Hz AC electric load is a kind of load used for continuous running and performance testing of products which can afford power supply of 400 Hz. The power of 400 Hz-AC afforded by medium frequency power supply can be fed into the grid in the form of 50 Hz sine wave. At the same time,both input and output current power factor can be of adjustable characteristic. The traditional resistive,inductive and capacitive load can be replaced by this electric load,which is a kind of energy saving product.
