摘要
研制了一种采用高频PWM方式控制的蓄电池充、放电装置。该装置集充、放电功能于一体,能实现对蓄电池恒流充电以及把蓄电池恒流放电时的能量回馈给电网,同时可以实现网侧电流正弦化和高功率因数、低谐波污染。
A novel charge-discharge device based on high frequency PWM is proposed in this paper. The device can be used in charging or discharging storage battery to electric net with fixed switching frequency. Experimental results prove that this device has the advantages of undistorted sinusoidal current waveform, high power factor and low AC harmonic.
