查询词典 fly by

In the voltage doubling rectifying circuit, the high voltage has been realized by the positive and negative way, and the voltage between the cathode and anode could reach 1700 V. In the fly-back switching high-voltage power supply, considering the requirements of each unit of the driving circuits on the power supply, the three-group voltage outputs including low-voltage outputs have been realized: 1600V/20mA,12V/500mA, 5V/50mA, in which UC3842 has been used to achieve pulse width modulation.

在倍压整流电路设计中，采用正、负电压方式实现高压，有效降低了阴阳极间所需的高压，最终两极间可产生1700V电压；在反激式开关电源电路设计中，利用UC3842芯片实现PWM调制，考虑到驱动电路各单元对电源的需求，设计了包括低压电源在内的三组电源输出：1600V/20mA，12V/500mA，5V/50mA。

The trajectory of the COM of the robot in stance phase is determined by solving the dynamic equation of the virtual leg, which can make the robot fly in the air. In flight phase, the COM of the robot moves as a free falling body.
