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:
