Indirect matrix converter (IMC) fed interior permanent magnet synchronous motor (IPMSM) drive is a novel solution for AC adjustable-speed drives with high performance and high efficiency. Position sensorless vector control technique is applied for the IMC fed IPMSM drive. Model reference adaptive system (MRAS) based rotor position estimation method is employed to estimate rotor position and speed...
In order to lower the cost and expand the working range of pulsewidth modulation (PWM)-inverter-fed interior permanent magnet synchronous motor drives, the control methods under the overmodulation mode with only a dc-link current sensor are investigated. The space vector modulation of the PWM inverter is analyzed in detail, and an adjustment scheme for the reference voltage vectors is developed to...
In order to lower the cost and expand the working range of PWM inverter fed AC motor drives, the control methods under over-modulation conditions with only a DC link current sensor are investigated. A basic phase current reconstruction algorithm is developed for PWM inverters. Taking the over-modulation into account, the space vector PWM strategy and the switching state distribution for PWM inverter...
The topology and control method of indirect matrix converter (IMC) is discussed in the paper. The space vector pulse width modulation (SVPWM) is employed on both of the rectifier stag and the inerter stage. The adjustment method of input power factor is presented based on the input current SVPWM of the rectifier stage. According to the polarity requirement of dc-link voltage, the regulation range...
A permanent magnet synchronous motor (PMSM) is applied to drive air-condition compressor in high speed operation for electric vehicle applications. In order to improve the performance, efficiency and reliability of the PMSM-compressor drive, a set of control strategies are developed. A double mode over-modulation method is proposed to enhance the voltage transfer ratio of PWM inverter and the output...
This paper proposes a novel algorithm for two-stage matrix converter to implement space vector pulse width modulation (SVPWM). Since the two-stage matrix converter has an intermediate dc link, the control process can be decoupled into rectifier stage modulation and inverter stage modulation. Conventionally, PWM algorithm for the rectifier stage is based on two larger source line voltages without zero...
