COMPONENT PARAMETER DESIGN
Design of Inductors
Assuming that IoB is the output current of
boundary conduction mode (BCM). The average currents flowing throughL 1 and Lm in BCM are equal
to half of the current ripple of L 1 andLm , respectively.

According to (62) and (63), the values of inductorsL 1 and Lm can be deduced.

Design of Capacitors
Considering the voltage ripples of capacitors, the values of capacitor
are designed suitable to increase the efficiency and stability. The
voltage ripples ΔvC1 , ΔvC2and ΔvCo can be derived as follows:
