For the content and feature that the present invention is further explained, specific embodiments of the present invention are carried out below in conjunction with attached drawing It illustrates.But implementation and protection of the invention is without being limited thereto.
As shown in Figure 1, the high-power voltage-controlled type negative resistance of resonance circuit is used for provided by the present embodiment, it is basic Principle is using the output electric current of the zero crossing information control exchange controlled current source of the resonance potential of resonance circuit, so that circuit Input current fundamental wave amount always with input voltage reverse phase, entire circuit is equivalent to a negative resistance 8, including connected exchange Controlled current source 1 and control circuit 3, the exchange controlled current source 1 and control circuit 3 are connected with resonance circuit 2 respectively, described Control circuit 3 includes switch drive module 4, zero crossing comparison module 5, phase compensation block 6 and the voltage sample mould being sequentially connected Block 7, the input voltage u of 7 sampling harmonic circuit 2 of voltage sample modulein, converted through phase compensation block 6 and zero crossing comparison module 5 For with input voltage uinThe square wave of complete reverse phase, the driving signal for generating switching device through switch drive module 4 are controlled to exchanging Current source 1, according to driving signal, the port between positive output end P and negative output terminal N generates fundamental current to exchange controlled current source 1 iF。
In above-mentioned negative resistance, input voltage fundamental wave amount and input current fundamental wave amount meet known to Ohm's law:
Exchanging controlled current source is made of the high-frequency electrical flow pattern inverter circuit of exportable high-frequency alternating current, can be outside Active power of output meets negative resistance property.The basic functional principle of high-frequency electrical flow pattern inverter circuit is by input voltage uinTurn The switching drive signal of same phase is turned to, for driving the switching tube in inverter circuit, thus the output fundamental current of control circuit iF, so that input voltage uinAt resonance frequency always with input current iinFundamental wave amount reverse phase always.
