摘要
A device and method for reducing current ripple to a light emitting diode array having a single stage power factor correction driver with an output voltage ripple that is reduced by using a linear current regulator connected in series between the single stage power factor correction driver and the light emitting diode array, which actively adjusts an equivalent impedance of the linear current regulator in correspondence with the output voltage ripple of the single stage power factor correction driver.
