In constant current-supplying PWM_POWER, the drain electrode of power tube Q01 meets DC power anode VDD, and the source electrode of power tube Q02 meets DC power cathode GND.Power tube Q01 source electrode and power tube Q02 drain electrode connect into test point A point.Power tube Q01 accepts to drive from the PWM of grid G 01 control of signal, and power tube Q02 accepts to drive from the PWM of grid G 02 control of signal.G01 and G02 are the gate drive signals of a pair of complementation, and duty ratio can regulate.The totem PWM power supply that power tube Q1, Q2 form is transformed into DC power supply VDD the PWM voltage signal of A point variable duty ratio, then by inductor L0, is transformed into the output current of high impedance, via the current output terminal B point output of constant current-supplying PWM_POWER.By changing duty ratio, just can change the output current size that B is ordered, and can not be subject to the impact of power coupling PWM_DRIVE.
In power coupling PWM_DRIVE, power tube Q03, Q04 and transformer T0 form transformer coupled formula push-pull circuit.The source electrode of power tube Q03, Q04 is all connected to DC power cathode GND.Power tube Q03 drain electrode connects the elementary top of transformer T0, power tube Q04 drain electrode connects the elementary tail end of transformer T0, and the elementary center-side of transformer T0 receives the supply current from the constant current-supplying PWM_POWER of B point input.B point is constant current-supplying PWM_POWER current output terminal, is also the current input terminal of power coupling PWM_DRIVE.Power tube Q03 accepts to drive from the PWM of grid G 03 control of signal, and power tube Q04 accepts to drive from the PWM of grid G 04 control of signal.G03 and G04 are also the gate drive signals of a pair of complementation, and duty ratio does not need to regulate.The electric current that B is ordered alternately drives the frequency pushing and frequency pulling commutation of signal to switch to the power drive signal of bipolarity frequency by power tube G03 or power tube G04 according to the PWM setting, by transformer T0, elementary current transformation is become to secondary high voltage again, via OUT and COM, be connected to load.
Between constant current-supplying PWM_POWER and power coupling PWM_DRIVE, be that current channel through the formed high impedance of inductor L0 is connected, make constant current-supplying PWM_POWER and power coupling PWM_DRIVE can distinguish the adjusting of complete independently to the adjusting of output voltage and output frequency.Thereby, realized the Orthogonal modification being independent of each other mutually of output voltage and output frequency.
In power coupling PWM_DRIVE, it is elementary that capacitor C0 is connected in parallel on transformer, and the self-inductance that capacitor C0, transformer T0 are elementary and secondary reflected umpedance have formed primary resonant; It is secondary that capacitor C1 is connected in parallel on transformer, and the self-inductance of T0 the level of electric capacity, transformer after capacitor C1 and the distinctive direct capacitance of ultrasound electric machine load are in parallel and elementary reflected umpedance have formed secondary resonance; Primary resonant and secondary resonance have formed coupled resonance in the lump.Choose reasonable capacitor C0, C1 and transformer T0(self-inductance and mutual inductance) parameter, can make two pwm powers drive the impedance matching frequency bandwidth of coupled resonance that topological structure forms, more single PWM drives, the impedance matching frequency bandwidth broadening several times of the power drive topological structure of series connection coupling, improved again the impedance matching between driver and load, reduced the impact that ultrasound electric machine load characteristic impedance variation produces simultaneously.
Transformer T0 is not only the output transformer of push-pull type commutation PWM driven unit, or the coupled resonance transformer of coupled resonance match circuit assembly in parallel, when guaranteed output obtains isolation and effectively transmits, also guarantee the stable of output voltage and output impedance, improved the energy conversion efficiency of driver.
Above examples of implementation are only unrestricted for the present invention is described, although the present invention is had been described in detail, one of skill in the art is to be understood that, to modification of the present invention and equivalent replacement, and do not depart from the spirit and scope of the present invention, within it all should be encompassed in claim scope of the present invention.
