Connection.Typically, it is working as the voltage across LC the two poles of the earth close to zero, it is that appropriate time promotes the conducting of BT power discharging transistors, holds
Perhaps electric current flows into transducing coil L, and is stored with magnetic energy.After BT power discharging transistors are conducting to some special time T-on
Ended, being stored in transducing coil L energy will be charged with anti-electric current to electric capacity C, energy by LC resonance circuit transducings,
It is straight to cause the voltage across LC the two poles of the earth to restart close to zero from the transducing cycle of BT power discharging transistors conducting.From BT power amplifier crystal
Pipe was the natural resonance time T-lc of LC resonance circuits, controls BT work(by the end of time of the voltage across LC the two poles of the earth close to zero
Put transistor turns time T-on, the power of electromagnetic heating structure can be controlled, this control, can by simple comparator and
Integrating circuit is completed.When BT power discharging transistors turn on, the energy for being stored in transducing coil L has depended on whether irony heat object
Material is a large amount of to be absorbed, and otherwise all energy can change into electric capacity C voltage, be attached directly to BT power discharging transistor collectors, and voltage is too high
BT power discharging transistors can then be punctured.
In other words, as long as control arrives BT power discharging transistor energy trouble free services to the power of electromagnetic heating structure and protection,
It is the core design of inexpensive electromagnetism heat radiating structure.To save cost, single-chip microcomputer has been used in many designs instead, further by part
Reduced number, cost also accordingly reduce, but function and core design are constant.
Electromagnetic Heating is mainly heated with the high power of the kitchen articles such as electromagnetic oven at present, on the market not favourable Electromagnetic Heating
