The embodiment of the energy-conservation aging technology of present embodiment electromagnetic oven is as shown in Figure 6.The energy-conservation aging equipment of electromagnetic oven comprises two parts, virtual iron pan device and inversion grid connection device.
Ferromagnetics pot body is substituted by a disccoil TB1 and FERRITE CORE behind thereof, and coil is the secondary winding of transformer, and FERRITE CORE has certain magnetic permeability, in order to constitute closed magnetic circuit with electromagnetic oven inside disccoil magnetic core.The output voltage of secondary winding obtains a smoother direct voltage that includes the power frequency pulsation through D1 bridge rectifier and L1C1 filtering.This direct voltage is the Boost boost type PFC power factor correcting through being made up of L2, Q1, D2, E1 again, realizes the input impedance constant function, and is Conversion of energy that direct current is stored on the electric capacity E1, Here it is virtual iron pan device.
Be stored in the direct current energy on the electric capacity E1, through the DC-AC inversion, convert to and line voltage with the alternating current of homophase frequently, and be transported on the shared electrical network, realize the recycling of energy, Here it is inversion grid connection device.
Through these two processes, realized the energy-efficient purpose that wears out or test of electromagnetic oven.
Describe in the face of principle of the present invention down.
It is as shown in Figure 1 that electromagnetic oven internal power circuit is generally single-end ortho-exciting resonance degaussing topology.The FERRITE CORE of ferromagnetics pot body and electromagnetic oven disccoil bottom constitutes closed magnetic circuit, and pot body itself has served as the secondary closing coil again simultaneously.Like this, electromagnetic oven disccoil TA1 has just constituted a transformer with the pot body.When electromagnetic oven was worked, the eddy current loss of iron pan and magnetic hysteresis loss caused a pot body to generate heat rapidly, and electric energy is converted into heat energy.Working principle of induction cooker that Here it is.
According to this operation principle, the physical model of electromagnetic oven power circuit is illustrated in fig. 1 shown below.Is the equivalence of the distributed constant of ferromagnetics pot body lumped parameter model, and the pot body is equivalent to transformer secondary magnetic core and secondary winding TB1, and its eddy current loss and magnetic hysteresis loss are equivalent to the total losses of a loss resistance of secondary.
We develop the physical model of pot body, obtain equivalent circuit model with expectation, and change energy into can utilize once more electric energy, carry the telegram in reply net through inversion.The physical model equivalence of ferromagnetics pot body is a transformer secondary winding and load resistance RL thereof, and is as shown in Figure 2.On this basis, increase a rectifier bridge D1 high-frequency alternating voltage rectification on the load resistance is become high frequency pulse dc voltage, as shown in Figure 3.Then, increase a LC filter circuit again the high frequency pulse dc voltage filter is become low frequency pulsating half-sinusoid voltage, as shown in Figure 4.In this conversion process, loss concentrates on the load resistance RL, and as far as electromagnetic oven, this model is the same with the effect of iron pan.
Load resistance RL is a pure resistive device that resistance is constant, its role is to be converted into heat energy to electric energy.Realizing energy-conservationly, must be the loss of this resistance electric energy by thermal power transfer.According to the principle of PFC power factor correction, input current waveform is followed voltage waveform, and the instantaneous ratio of voltage and electric current is a certain steady state value, has the dimension of resistance, promptly sees into from input port, and equivalence is the effect of a pure resistance.We replace load resistance to the PFC power factor correcting, so just have been converted into the electric energy that can utilize once more to the heat energy loss on the load resistance, and are as shown in Figure 5.
Through above evolution process, we are the Conversion of energy of pot body loss the direct current energy that can utilize once more, and are stored on the electrochemical capacitor E1.Through further DC-AC inversion conversion, this dc energy is converted into ac energy again, and is delivered to AC network, supplies other power consumption equipment to use, and is as shown in Figure 6.The energy-conservation aging operation principle of electromagnetic oven that Here it is, the energy Flow relation is as shown in Figure 7.Electromagnetism is worn out, at first through electromagnetism being added the 220V civil power of AC network, start the work of electromagnetic oven, virtual (simulation) iron pan receives the variation conversion of the magnetic energy that is produced by electromagnetic oven work and reclaims from electric energy, through inversion grid connection, gets back in city's electrical network.
