A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power Converters can include simpler tools such as transformer or more complex like a resonant converter.
The voltage, or potential difference between two terminals or nodes provided by a voltage source is defined as having a value of one volt, when one joule of energy is used in moving one coulomb of electric charge between those two terminals.
The task of a power converter is to process and control the flow of electric energy by supplying voltages and currents in a form that is optimally suited for the user loads. Energy was initially converted in electromechanical converters (mostly rotating machines).
A voltage converter is an electric power converter which changes the voltage of an electrical power source. It may be combined with other components to create a power supply. AC voltage conversion uses a transformer.
Volt is the electrical unit of voltage. One volt is the energy of 1 joule that is consumed when electric charge of 1 coulomb flows in the circuit. 1V = 1J / 1C. Ampere (A) Ampere is the electrical unit of electrical current. It measures the amount of electrical charge that flows in an electrical circuit per 1 second. 1A = 1C / 1s. Ohm (Ω) Ohm ...
Ohm’s Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit as shown below. By knowing any two values of the Voltage, Current or Resistance quantities we can use Ohms Law to find the third missing value.
Express electrical power in terms of the voltage and the current; Describe the power dissipated by a resistor in an electric circuit; Calculate the energy efficiency and cost effectiveness of appliances and equipment
