2. Boost converter - Wikipedia

   en.wikipedia.org/wiki/Boost_converter

   A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output . It is a class of switched-mode power supply (SMPS) containing at least two semiconductors, a diode and a transistor , and at least one energy storage element: a capacitor , inductor , or the two in ...

3. Transformer - Wikipedia

   en.wikipedia.org/wiki/Transformer

   Transformers are used to change AC voltage levels, such transformers being termed step-up or step-down type to increase or decrease voltage level, respectively. Transformers can also be used to provide galvanic isolation between circuits as well as to couple stages of signal-processing circuits.

4. Buck–boost converter - Wikipedia

   en.wikipedia.org/wiki/Buck–boost_converter

   From the above expression it can be seen that the polarity of the output voltage is always negative (because the duty cycle goes from 0 to 1), and that its absolute value increases with D, theoretically up to minus infinity when D approaches 1. Apart from the polarity, this converter is either step-up (a boost converter) or step-down (a buck ...

5. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   A schematic representation of long distance electric power transmission. From left to right: G=generator, U=step-up transformer, V=voltage at beginning of transmission line, Pt=power entering transmission line, I=current in wires, R=total resistance in wires, Pw=power lost in transmission line, Pe=power reaching the end of the transmission line, D=step-down transformer, C=consumers.

6. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   Transformers are used in power converters to incorporate electrical isolation and voltage step-down or step up. The secondary circuit is floating, when you touch the secondary circuit, you merely drag its potential to your body's potential or the earth's potential. There will be no current flowing through your body.

7. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   If the output is required to be isolated from the input, as is usually the case in mains power supplies, the inverted AC is used to drive the primary winding of a high-frequency transformer. This converts the voltage up or down to the required output level on its secondary winding. The output transformer in the block diagram serves this purpose.

8. Electric power distribution - Wikipedia

   en.wikipedia.org/wiki/Electric_power_distribution

   From the generating station it goes to the generating station's switchyard where a step-up transformer increases the voltage to a level suitable for transmission, from 44 kV to 765 kV. Once in the transmission system, electricity from each generating station is combined with electricity produced elsewhere.

9. Chopper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Chopper_(electronics)

   Take a general step-up chopper with voltage source which is in series with the inductor , diode and the load with average voltage . The chopper switch would be in parallel with the series diode and load. Whenever the chopper switch is on, the output is shorted.
