Abstract :
The most widely used types of pulse-width-modulated (PWM) DC/DC converters are dynamically modeled at low frequencies in terms of two-port networks. Four DC parameters fully characterize each type of regulator. These closed-loop parameters are related to six transfer functions relevant to the open-loop circuit. Practical dynamic problems involving stability, electromagnetic cleanness, and transmission of disturbances from the load to the voltage source (and vice versa) can be solved on the basis of the formula given
