How to do simulation of this problem using PSIM?

Henderson · Answer

Answer:

To calculate the gain kPWM for a switch-mode DC-DC converter using PSIM, you'll need to create a model of the converter, including the PWM controller. With the triangular waveform signal set at 25kHz and a peak value of 1.5V, adjust kPWM accordingly. The simulation with the given input DC source voltage can then be run. This is only a simplified summary, actual implementation could be more complex.

Explanation:

In the context of a switch-mode DC-DC converter with a PWM controller, the gain kPWM can be defined as the ratio of the control voltage to the peak value of the triangular waveform signal. In your case, the peak value of the triangular waveform signal (Vtri) is 1.5 V. However, additional information such as the control voltage is required to calculate the gain kPWM.

In general, to simulate this problem in PSIM, you would need to create a model of the switch-mode DC-DC converter circuit including the PWM-controller. The waveform generator in PSIM can be used to create the triangular wave signal at the specific frequency of 25kHz and peak value of 1.5V. The gain kPWM can then be adjusted in the controller settings based on the calculated value. Running the simulation will then allow you to observe the behavior of the converter for different input DC source voltages (Vd).

Please note that this is a simplified overview of the simulation process and the actual implementation could be more complex, depending on the specifics of your switch-mode DC-DC converter.
