| Summary: | 碩士 === 國立臺灣科技大學 === 工程技術研究所 === 81 === The thesis is exploring the induction motor drive system based
on DSP(Digital Signal Processor) for fully-digital controll .
It use voltage space vector PWM as system control algorithm and
take advantage of the high speed calculation of DSP and high
switching、high capacity and low loss characteristic of IGBT(
Isolation Gate Bipolar Transistor). The driver 、power module
and three phase AC source rectifier of system all use hybrid IC
, so that decrease the system area and simplify design jobs.
The power source of the control system and protection circuit
is supplied by one switching power supply . In order to promote
the system's realibility. The system's protection circ- uit
include voltage protection 、current protection circuit. and
logic error signal detecting circuit. The thesis is just a open
loop induction motor drive system,thereafter, it can be added a
few periphrells 、interface and speed controller, then the
system will be promoted . Finally, we make three experiences to
verify the system's performance.
