In the present embodiment, the pwm control signal circuit is that a kind of control instruction that the load circuit of colorful ultrasonic diagnostic apparatus is sent is got a value and is sent to the PWM high tension generator at low side, the PWM high tension generator is started working prior to before the high-voltage converter conversion when pulse begins, and when end-of-pulsing, lag behind after the high-voltage converter conversion out-of-work circuit again.
Correspondingly, in the present embodiment, the changeover control signal circuit is that a kind of control instruction that the load circuit of colorful ultrasonic diagnostic apparatus is sent is got a value and is sent to high-voltage converter high-end, make high-voltage converter begin time delay in pulse and be later than the PWM high tension generator and change, and the circuit that when end-of-pulsing, finishes in the PWM high tension generator in advance.
Present embodiment can be realized the high pressure conversion of colorful ultrasonic diagnostic apparatus in conjunction with a PWM high tension generator, thereby make the colorful ultrasonic diagnostic apparatus high pressure conversion not only simply but also convenient, and because number of elements is less, make system bulk, weight all less, reduced system's heating and energy loss.
Embodiment two:
See also Fig. 4, a kind of structure chart that is applied to the high pressure conversion equipment of colorful ultrasonic diagnostic apparatus that Fig. 4 provides for the embodiment of the invention.As shown in Figure 4, this device can comprise PWM high tension generator 401, pwm control signal circuit 402, high-voltage converter 403 and changeover control signal circuit 404.
Wherein, pwm control signal circuit 402 be used for to receive the control instruction that the load circuit of colorful ultrasonic diagnostic apparatus sends, and control instruction is sent to PWM high tension generator 401;
PWM high tension generator 401 is used for producing HT waveform and exporting high-voltage converter 403 to according to this control instruction; Wherein, this HT waveform is equal adjustable pulse voltage of an amplitude and time;
Changeover control signal circuit 404 is used for the conversion instruction of the load circuit transmission of reception colorful ultrasonic diagnostic apparatus, and this conversion instruction is sent to high-voltage converter 403;
High-voltage converter 403, be used for according to this conversion instruction with the HT waveform of PWM high tension generator 401 outputs be converted to amplitude less than 100 volts and conversion speed smaller or equal to 600 delicate high pressure and outputs.
As a kind of optional embodiment, the PWM high tension generator can become the 12V voltage transitions HT waveform and export high-voltage converter to according to this control instruction.Wherein, the concrete structure of PWM high tension generator and function belong to general knowledge known in those skilled in the art, and the embodiment of the invention is not given unnecessary details.
In the present embodiment, the duty of PWM high tension generator 401 is controlled by pwm control signal circuit 402.Wherein, the control instruction that load circuit (ultrasound emission circuit) sends and switching signal enter pwm control signal circuit 402 and changeover control signal circuit 404 separately, wherein, the conducting voltage of pwm control signal circuit 402 is lower than the conducting voltage of changeover control signal circuit 404, so pwm control signal circuit 402 a period of time conducting in advance.After after a while, PWM high tension generator 401 output PWM output HT waveform P1, at this moment changeover control signal circuit 404 beginning conductings, high-voltage converter 403 work, high-voltage converter 403 is opened its inner voltage switch, the high-voltage pulse P of system's output at this moment rises moment, has satisfied the zooming requirement of load circuit of colorful ultrasonic diagnostic apparatus.
And when HT waveform P1 finishes, changeover control signal 404 is because the conducting voltage height, can when finishing, end prior to pwm control signal circuit 402 HT waveform P1, send pick-off signal in advance, at this moment high-voltage converter 403 will be outputted to low-pressure state, export a complete demand high-voltage pulse P.
See also Fig. 5, Fig. 5 is the sketch map that concerns of the high-voltage pulse P that exports of HT waveform P1 and the high-voltage converter 403 of PWM high tension generator 401 output.Wherein, P also is the output high-voltage pulse of high pressure conversion equipment, and P1 is the output high-voltage pulse of the PWM high tension generator 401 of high pressure conversion equipment.As can be seen, P1 is the tangent line relation that is similar to that a point contacts with P, and the utmost point is similar to the envelope in the high-frequency circuit, and therefore, the high pressure conversion equipment that provides in the present embodiment can be called " envelope formula high pressure conversion equipment " again.
