What is the state space modulation mapping method of three-phase half-bridge SPWM inverter VSV-PWM?

What is the state space modulation mapping method of three-phase half-bridge SPWM inverter VSV-PWM?

Posted on February 28, 2022February 28, 2022 by admin

The three-phase half-bridge SPWM inverter VSV-PWM state space modulation mapping method is also called the six-step PWM mapping method. It is a drawing method that makes the magnetic flux trajectory tend to be circular, or a method of finding the magnetic flux trajectory using the drawing method. The basic idea is to use numerical control…

Voltage space phasor representation of three-phase half-bridge SPWM inverter

Posted on February 8, 2022February 8, 2022 by admin

The voltage space phasor representation is a method that directly combines the SPWM and the circular trajectory of the motor flux linkage, which was proposed by J.Holtz in 1983. According to the principles of electrical engineering, the sine quantity can be represented by a complex number, that is, it can be represented by the projection…
