First an AC supply of 230V and 50Hz is rectified into DC through the rectifier. Then this rectified DC works as an input to the H bridge Inverter (MOSFET Gate Driver Circuit) Two complementary pairs of Sinsusoidal PWM pulses is applied across the gates of these MOSFETS. Switching frequency used for driving MOSFET gate is 10 kHz. The sinusoidal PWM is generated through the microcontroller whose frequency and magnitude is controllable. The inverter generates a sinusoidal output that is filtered through a 2nd order LC filter. The LC filter mitigates the high frequency harmonics and converts it into a pure sine wave. Now the magnitude of the sine wave is varies from 0 to 230V and applied to the high voltage transformer. The transformer steps up this voltage such that the output rises from 0 to 35 kV with a fixed rate of rise of voltage of 1kV/s. This slew rate can be changed to 2kV/s or 0.5kV/s according to the requirement. This high voltage is applied across the electrodes that are immersed in the testing oil. How do I simulate this whole process in Simulink to get a perfect voltage slew rate of 2kV/s till 36kV/s ?
