【摘要】：隨著低壓大電流開關(guān)電源在各行業(yè)中廣泛應(yīng)用,用戶對其電能質(zhì)量有了更高的要求。由于這種大功率開關(guān)電源產(chǎn)生的諧波電流對電網(wǎng)污染嚴(yán)重,電源功率因數(shù)較低,因此必須采取可靠措施對其改善。文中采用三相單開關(guān)Boost型PFC電路,通過諧波注入技術(shù)調(diào)制開關(guān)管的占空比,以實現(xiàn)抑制諧波和校正功率因數(shù),并通過仿真驗證了該方法的可行性和有效性。
[Abstract]:With the wide application of low-voltage and high-current switching power supply in various industries, users have higher requirements for its power quality. Because the harmonic current generated by this high-power switching power supply seriously pollutes the power network, the power factor of the power supply is low. Therefore, it is necessary to take reliable measures to improve it. In this paper, three-phase single-switch Boost type PFC circuit is used to modulate the duty cycle of switch through harmonic injection technology in order to suppress harmonics and correct power factor. The feasibility and effectiveness of the method are verified by simulation.
