Electric forklifts commonly used power supplies use a linear power supply of a power frequency transformer (iron core, 50 Hz) and two major categories of switching power supplies using high-frequency transformers (magnetic cores, thousands Hz). BeThe principle of the switching power supply is to convert the AC electrical electrical electrical electrical current of the power frequency (50 Hz) into a high frequency current, and then the high-frequency transformer becomes low pressure and outputs low pressure DC. Since the high-frequency transformer volume of the same power is much smaller than the computer, the smaller the volume, the size is small, so it can be done, the size is small, the weight is light, and thus is widely adopted. The voltage regulation of the electric forklift is mainly achieved by controlling the oscillating frequency, and because of this, the electric forklift switching power supply is not good in the case of shielding, if it is used to charge the interference of the harmonic, resulting in a loss of regulating performance. Voltage fluctuation, or due to its high frequency interference makes frequency transformation. At the same time, if the switching power supply is not good, once a fault occurs, its voltage may suddenly rise a lot and burn the battery. Therefore, the linear power supply should be a certain development space.
