Problems solved by technology

However, at high speeds, drives typically use only the high-speed motor, leaving the low-speed motor idle
In this way, when running at high speed, the low-speed motor is useless, which limits the application of the low-speed motor

Embodiment Construction

[0056] Please refer to Figure 1A, which shows a functional block diagram of a multi-drive device according to an embodiment of the present invention. The multi-drive device 10 is, for example, vehicles, machine tools and other devices requiring output power, which includes a first drive device 100 , a drive circuit 200 , a second drive device 300 and a drive circuit 400 .

[0057] Please refer to Figure 1B , which shows Figure 1A The circuit diagram of the multi-drive device. The first driving device 100 is coupled to the second driving device 300 through the driving circuits 200 and 400 . The first driving device 100 is, for example, a three-phase motor, which includes a first inductor L1 , a second inductor L2 and a third inductor L3 , but the first driving device 100 can also be other driving devices including inductors. The type of the second driving device 300 can be similar to that of the first driving device 100 , and the inductance value of the second driving devi...

Abstract

Provided are a multi-drive device and a drive circuit thereof. The drive circuit coupled to a first drive apparatus and a second drive apparatus includes three switch units. Each switch unit includes a first switch, a second switch, a third switch and a fourth switch. The first switch and the second switch are connected in series. The third switch in series connection with the fourth switch is coupled between the first switch and the second switch. An I inductor of the first drive apparatus is coupled between the third switch and the fourth switch, wherein i ranges from 1 to 3. In a high speed mode, the first switch and the third switch from one unit of the three switch units are conducted while the second and fourth switches are cut off, and the first and third switches from another unit of the three switch units are cut off, the second switch is conducted and the fourth switch is conducted or cut off. Therefore, boosting of the second drive apparatus is achieved.

Description

technical field [0001] The invention relates to a driving circuit and a multi-driving device using the same, in particular to a driving circuit capable of improving high-speed performance and a multi-driving device using the same. Background technique [0002] Traditional driving devices usually combine high-speed motors and low-speed motors to improve their performance at low speeds and high speeds. However, under high speed operation, the driving device usually uses only the high speed motor, leaving the low speed motor idle. In this way, when running at high speed, the low-speed motor is useless, which limits the application of the low-speed motor. Contents of the invention [0003] The invention relates to a driving circuit and a multi-driving device using the same. In one embodiment, the application of low-speed motors can be improved, and the high-speed performance of the multi-driving device can be improved. [0004] According to an embodiment of the present inven...
