According to an aspect, a non-regulated power converter includes a plurality of switching tank converter (STC) modules configured to be connected in parallel and to a load. The plurality of STC modules includes a first STC module configured to generate a first output current and a second STC module configured to generate a second output current. The first STC module includes an output current (OC) measuring circuit configured to measure a value of the first output current, and a dead time (DT) adjustor configured to compare the value of the first output current with a value of a minimum output current provided by the plurality of STC modules. The DT adjustor is configured to adjust a dead time in response to the value of the first output current being greater than the value of the minimum output current.

Systems, devices and methods using three separate switching phases for a buck-boost regulator are disclosed. The regulator may operate in a boost mode, a buck mode or in a buck-boost mode. The output voltage remains constant through mode changes and the ripple voltage is well-controlled. If the input voltage is lower than the output voltage by a first threshold, the regulator operates in boost (step-up) mode. If the input voltage is higher than the output voltage by a second threshold, it operates in buck (step-down) mode. The regulator operates in the buck-boost mode when the difference between the input and output voltages is within a certain range.
