Design and Implementation of CRM PFC Converter to Minimize Inductor Peak Current for LED TVs

A power factor correction (PFC) converter is essential for a switching mode power supply (SMPS), which is used in light-emitting diode televisions to comply with the harmonic current standard of IEC 61000-3-2 Class D. However, because of the high inductor peak current of a boost PFC converter, large...
