Switched DC to DC converters offer a method to increase voltage from a partially lowered battery voltage thereby saving space instead of using multiple batteries to accomplish the same thing. Additionally, the battery voltage declines as its stored energy is drained. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).

DC-DC Converter Input and Output Voltage TestĭC to DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. The control circuit controls the on and off time of the switch tube to keep the output voltage unchanged. The output voltage Vo is divided by the voltage divider composed of R 1 and R 2, and the signal of the output voltage is fed back to the control circuit. The diode VD 1 is a freewheeling diode to form a circuit loop. When the output voltage is going to drop, the energy in the capacitor C 2 is also discharged to R L, maintaining the output voltage unchanged. When VT 1 is off, the energy stored in the inductor L 1 continues to supply power to R L.
In this process, energy is stored in the capacitor C 2 and the inductor L 1. When VT 1 is turned on, the input voltage V i supplies power to the load R L through the inductor L 1, and at the same time it also charges the capacitor C 2. The basic working principle circuit of the step down converter is shown in the figure. The output current of the step-down DC to DC converter is relatively large, mostly hundreds of milliamperes to several amperes, so it is suitable for occasions with relatively large output current. There are three types DC converter on ATO.com, including boost converter, buck converter and boost-buck converter. DC-DC Converter Working PrincipleĭC to DC means DC to DC conversion. They are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily.
But boost converters are the opposite, to step up 12V to 24V/36V/48V, 24V to 48V.
Buck converters are designed to step down 24V/36V/48V to 12V, 48V to 24V.
#Dc power converter series#
ATO provides DC-DC buck converters, DC-DC boost converters, and DC-DC boost buck converters three converters series with a wide power range and cheap price for selection. A DC to DC converter is a type of electric power converter that converts a source of direct current (DC) from one voltage level to another.
