energy sources require switching regulators as an interface to a load with high
efficiency, small size, proper output regulation, and fast transient response.
Moreover, due to the nonlinear behavior and switching nature of DC-DC power
electronic converters, there is a need for high-performance control strategies.
This work summarized the dynamic behavior for the three basic switch-mode DC-DC
power converters operating in continuous conduction mode, </span><i><span style=\"font-family:Verdana;\">i.e.</span></i><span style=\"font-family:Verdana;\"> buck, boost, and buck-boost. A controller was designed using
loop-shaping based on current-mode control that consists of two feedback loops.
A high-gain compensator with wide bandwidth was used in the inner current loop
for fast transient response. A proportional-integral controller was used in the
outer voltage loop for regulation purposes. A proce</span><span style=\"font-family:Verdana;\">dure was proposed for the parameters of the controller that ensures
closed-loop</span><span style=\"font-family:Verdana;\"> stability and output voltage regulation. The design-oriented
analysis was applied to the three basic switch-mode DC-DC power converters.
Experimental results were obtained for a switching regulator with a boost converter
of 150 W, which exhibits non-minimum phase behavior. The performance of the
controller was tested for voltage regulation by applying large load changes.
