Three phase inverter circuit consists of six switches connected in three legs, converts input dc link voltage in to corresponding three phase ac voltage. Microcontroller and driver circuit is used to control on/off time of switching devices in a proper sequence in a particular time used in the main inverter circuit.
A three-phase Voltage Source Inverter (VSI) with SPWM (Sinusoidal Pulse Width Modulation) is a type of inverter that converts DC voltage into three-phase AC voltage with sinusoidal waveforms. It works by varying the pulse width of a high-frequency carrier signal according to the instantaneous amplitude of a reference sinusoidal waveform.
While some special controller ICs are also available that are designed and fabricated for three phase PWM generation and control purpose. PWM generation digitally require only knowledge of internal architecture of controller and good programming skill. In this work microcontroller 89C52 is used for three phase PWM generation and inverter control.
Abstract: A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter.
The following steps illustrate the algorithm to obtain the three phase PWM waveforms using microcontroller; Access the three phase synchronous PWM pulse width data values from look up table using three different pointers to look up table. Send the desired PWM code pattern at port pins. Set the timer value with lowest pulse width value first.
In addition analog method of three phase PWM generation requires accurately designed phase shifter circuits and other circuit. Also the response of analog circuit may get affected by environmental conditions, noise, changes in the voltages and currents in the circuit and so on.
