Abstract: DOI: 10.24193/subbeng.2022.1.10 Published Online: 2022-11-11 pp. 105-112 VIEW PDF FULL PDF: VOL.67, No.1, 2022 The paper presents a way of accomplishing a non-contact excitation by electromagnetic waves generated from a system that includes WiFi microcontroller, H-Bridge and coil. The ESP 32 microcontroller software achieves PWM signal, which follows’ a sinusoidal shape of variable frequency. The PWM signal drives the H-bridge resulting in a more powerful electric signal that also drives the coil, accomplishing in this way the pseudo-sine electromagnetic wave. The source code from microcontroller provides variable frequency and working period as well. The main features of the system are 0.5 to 3000 Hz, working periods between 0.1 and 10 seconds, the possibility to achieve more than one working period with standby periods in between. Keywords: sine electromagnetic wave, WiFi microcontroller, H-bridge, software PWM, vibration based modal analysis.
