Explain the energy conversion in a battery-powered resistive circuit when the current is flowing: chemical to thermal to electric. Calculate the emf from the circuit below. How can the formula for power (power = work done/time taken) be explained? What is the resistance of a circuit with a...
AC–DC power conversionresonant power conversionAnalysis and design of a single-stage $LLC$ resonant converter are proposed. A single-stage converter uses only one control signal to drive two power converters, a power factor corrector (PFC) converter and a dc/dc converter, for reducing the cost...
1. Transformer: The transformer is the heart of an AC-DC power supply, as it converts the AC voltage from the mains or other sources to the required DC voltage level. A transformer consists of two or more coils of wire wrapped around a magnetic core, which allows the transfer of energy...
DC-DC refers to the conversion of distinct DC power values from one to the other. It can be called a DCDC converter if it meets this definition, which includes LDO. The device that switches DC to (to) DC is known as DCDC, according to popular belief. Step-up, step-down, step-up/...

At rated conditions, the C1 capacitor is charged to the output voltage. Therefore, the C1 capacitance is selected according to the following formula: 𝐶1=𝐼Lm𝑈out𝑡C,C1=ILmUouttC, (6) where tC is the time period when the C1 capacitor is discharging (Figure 3c). The ILm and U...
The converter is a power electronic device, used to convert DC to AC. These devices use switching devices. The DC to AC conversion can be done among 12V, 24V, 48V to 110V, 120V, 220V, 230V, 240V with supply frequency 50Hz/60Hz. For a better understanding of this concept here is a ...
Efficiency is the percentage of the input power delivered to the output. It can be calculated with the following formula: As mentioned above, the efficiency of DC-DC converters can vary a lot. In some cases, this parameter is considered crucial. For example, if the device is powered by bat...
In this article, we have listed all the important formulas and equations related to DC generators used in different electrical practices like design, simplify, and analysis. This page can serve as a DC generator formula handbook for electrical engineering students and professionals....
A new DC–DC buck–boost converter with a wide conversion ratio is presented in this paper. The proposed buck–boost converter consists of a combination of modified boost converter and ZETA converter, which has the advantages of both converters such as c
