Published Date: 04/23/2013

Description

In a single ended primary inductance converter (SEPIC) design the output voltage can be higher or lowerthan the input voltage. The SEPIC converter shown in Figure 1 uses two inductors: L1 and L2. The twoinductors can be wound on the same core since the same voltages are applied to them throughout theswitching cycle.
