Abstract
This paper proposes a simple circuit model to estimate output voltage fluctuation in paralleled converter system with optimized on-off control. The optimized on-off control method changes the number of active converter modules to minimize power losses in paralleled system according to load current. However, it causes voltage fluctuation in transient response. Output voltage fluctuation due to the on-off control is estimated with proposed simple circuit model. The estimation is verified by accurate circuit simulation. Simple guideline for circuit components is also given to meet a specific output voltage tolerance.
