Operation at wide input range – PWM modulated Converters
− The
PWM modulated converters are not able to increase gain by
changing duty cycle. Therefore the VBUS – Vmin has to be small (2030V).
− The
whole energy has to by stored in DC bus capacitor
− Example
of DC bus capacitor calculation
Pout = 500W
VBUS = 400V
Vmin =370V
fmin = 45Hz

Operation at wide input range – Resonant Converters
− Some
resonant converters can increase gain over 1 by changing
switching frequency. Therefore the VBUS – Vmin can be much higher
than for PWM modulated converters.
− Example
of DC bus capacitor calculation
Pout = 500W
VBUS = 400V
Vmin =200V
fmin = 45Hz
C
2P
 185 F
fmin(VBUS  Vmin )
DC Bus capacitor can be significantly smaller 185 F versus
