8.7.3 Efficiency
An efficiency of 75 % at maximum output power can be achieved for a complete converter
designed for universal mains.
8.7.4 Ripple
A minimum ripple is obtained in a system designed for a maximum duty factor of 50 %
under normal operating conditions, and a minimized dead time. The magnitude of the
ripple in the output voltage is determined by the frequency and duty factor of the
converter, the output current level, and the value and ESR of the output capacitor.
