A closed-form linearized relation between volt-second mismatch and inductor current offset is derived. This relation is then verified through simulation and experimental results using two prototype circuits comprised on an inductively loaded full-bridge and a dual active bridge (DAB) converter. 展开 ...
The relation between the power types. Power factor determines the system's power efficiency and is the ratio between true power and apparent power. The lower the power factor, the less efficient a power system is. The power factor lags with inductive load and leads with capacitive load. Resist...
Sis the apparent power in Volt-amper [VA] Vrmsis the rms voltage = Vpeak/√2in Volts [V] Irmsis the rms current = Ipeak/√2in Amperes [A] Real / reactive / apparent powers relation The real power P and reactive power Q give together the apparent power S: ...
The other fraction of power is called reactive power. Reactive power does no useful work, but it is required for the active work to be done. We denote it with ‘Q’ and mathematically is given by: Q = Reactive power = Total electrical power.sinφ and its unit is VAR (Volt-Amp Reacti...
Such energy is given by the following relation: 1 Ec = 2 · C · U2 where: • C is the capacitance; • U is the voltage applied to the terminals of the capaci- tor. Because of their capability of storing and delivering energy, capacitors are used as basic element for the ...
The formulation of the original instantaneous reactive power introduces instantaneous imaginary power to complete the description of the process of energy transfer between source and load. Second, the definition given in (3.6) introduces an instantaneous imaginary power whose average value is the average...
at a given point. • Voltage is a scalar quantity. The SI unit of voltage is the volt, such that 1 volt = 1 joule/coulomb. • 230V is received for domestic purposes in India. Definition : • Current is defined as the movement of electrons inside a conducting material. • In ...
