用于振荡器的激励电路
摘要：
本发明涉及一种用于激励振荡器(3)的激励电路(11)。所述激励电路(11)包括：包括第一端和第二端的第一电感器(LD)；连接至所述第一端的电能量源(13)；以及连接至所述第二端并连接至振荡器的开关电路。所述开关电路被配置成至少运行在关闭状态和开启状态，在所述关闭状态下其被配置成不向振荡器(3)提供电能，在所述开启状态下其被配置成向振荡器(3)提供电能。所述第一电感器(LD)布置成当开关电路处于关闭状态时将能量存储在其磁场中，当开关电路处于开启状态时，开关电路布置成利用存储在磁场中的能量的至少一部分将电流冲击从电能量源(13)传送至振荡器(3)。
摘要（英）：

The present invention concerns a drive circuit (11) for driving an oscillator (3). The drive circuit (11) comprises a first inductor (LD) comprising a first terminal and a second terminal; an electrical energy source (13) connected to the first terminal; and a switching circuit connected to the second terminal and to the oscillator. The switching circuit is configured to operate at least in an off state, where it is configured not to feed electrical energy to the oscillator (3), and in an on state, where it is configured to feed electrical energy to the oscillator (3). The first inductor (LD) is arranged to store energy in its magnetic field when the switching circuit is in the off state, and, when the switching circuit is in the on state, the switching circuit is arranged to use at least some of the energy stored in the magnetic field to deliver a surge of current from the electrical energy source (13) to the oscillator (3).
