摘要
传统的两级APFC采用两套控制电路和至少两个功率开关管,增加了电路复杂程度及成本。随着PFC/PWM两级复合控制芯片的产生,两级APFC的这一缺陷可以得到大大改善。通过对PFC/PWM两级控制复合芯片ML4824的两级APFC技术进行的测试与分析,分析了将其用于带PFC的蓄电池充电器中的可行性。
The traditional two-stage APFC adopts two set of Control circuit and at least two power switch tubes, which makes the circuit much more complicete with high cost. And this defect of twostage APFC has been improved as the PFC/ PWM this two,stage compound control chip appears. After the test and analysis On the two,stage APFC technology of PFC/ PWM two-stage compound control chip ML4824, the author of this essay elaborates the possibility to ultillze this technology in the battery charger with PFC.
