PWM CONTROLLER BASICS A) Inverter Basics All PWM inverters are designed to vary the speed of an A-C induction ... First the controller converts the user supplied sine- wave power to a fixed D-C voltage, usually through a diode bridge full wave rectifier. ... Figure 6 - PWM Block Diagram When we examine the speed torque curve in the area between the ... noise, the result of motor lamination excitation, as well as how closely the PWM controller approximates a pure sine- wave.
