Abstract :
Multiple output DC/DC converters are commonly used in electronics equipment. These converters have typical problems such as line, load and cross regulations. The family of converters presented in this paper works at fixed switching frequency and it is characterized by using a combination between pulse width modulation and pulse delay control (PWM-PD), in order to reduce the number of regulator components in the converters. This control technique allows a bigger number of control parameters to be obtained than the number of controlled components. Finally, experimental results in a converter with three insulated outputs are presented
