Fast Method for the Iron Losses Prediction in Inverter Fed Induction Motors [PDF]
In this paper an easy method for the iron loss prediction in PWM inverter fed induction motors is presented. The method was initially proposed and validated for the prediction of the iron losses in non-oriented soft magnetic material with PWM supply ...

Abstract The paper describes various modified algorithms of classical sinusoidal pulse width modulation (PWM) serving for a three-phase two-level inverter control. The paper presents the results of a research of 3 PWM versions with varying duty cycle parameters and frequency of the pulse signal modulation.

Stairstepping on PWM inverters explained [PDF]
When supplying an induction motor by a PWM-inverter, reflection phenomena occur if the supply is done through long motor cables. Several papers discuss by simulations or experiments the overvoltage appearing at the motor terminals. The consequences of the overvoltage are a widespread topic. This paper deals with other reflection phenomena observed with

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

Analysis of VCO based noise shaping ADCs linearized by PWM modulation [PDF]
Nonlinearity is one of the main problems associated with VCO based noise shaping ADCs. Their open loop architecture does not permit correction of the nonlinear voltage to frequency response of the VCO by feedback.

A new discrete sampling based pulsewidth modulation (PWM) strategy is presented which closely reproduces the characteristics of analogue hysteresis band modulation. This sampling based strategy does not require the solution of nonlinear transcendental equations, which are characteristic of the analogue method and therefore limit its application.
