DC-DC Converters

A DC-DC converter, also known as a DC-to-DC converter, is a type of power converter that takes a direct current (DC) input and converts it to a different direct current (DC) output or to an alternating current (AC) output. DC-DC converters are typically used to step up (boost), step down (buck), or invert DC sources. DC-DC converters can be found in a variety of applications, including portable electronics, automotive, industrial, power supplies, communications systems, and more.

VI-BTN-IX Application Field and Working Principle

The VI-BTN-IX converter is a three-terminal DC-DC converter that switches between two input sources, allowing for efficient operation and protection of the output voltage. It is typically used in applications such as telecommunications, power supplies, and motor control. This converter is particularly useful for applications with multiple power sources, such as solar, wind, and battery power, as it allows for easy optimization of the power output between sources.

The VI-BTN-IX converter has three input terminals: an enable pin, a voltage pin, and an enable-disable pin. The enable pin is used to control whether the converter is on or off. When the enable pin is set to high, the converter is in the “on” mode and transistors switch between the two inputs. When the enable pin is set to low, the converter is in the “off” mode and no switching occurs. The voltage pin is used to control the output voltage of the converter. The enable-disable pin can be used to override the enable pin and force the converter into the “off” mode.

The VI-BTN-IX converter has two switch transistors that are driven by two pulse width modulators (PWMs). The PWMs control the on-off status of the transistors, which controls the flow of current through two diodes. The two diodes act as rectifiers and will output a DC voltage from the two input source voltages. The output voltage is determined by the on-off status of the two transistors and will vary based on the duty cycle of the PWMs.

The VI-BTN-IX converter is able to switch between two input sources and provide protection from over-voltage at the output. The converter can be configured to provide a wide range of output voltages and can be used in a variety of applications. Additionally, the use of two diodes allows for efficient power conversion and the ability to regulate the output voltage over a wide range.
