IoT based Smart Fan Dimmer with suppressed Humming Sound and Nonlinear Effect of Inverter

To address power shortages in third-world countries, other energy sources such as uninterrupted power supplies that charge batteries while line voltage is available are employed. Inverters on the market contain output voltage waveforms that do not provide pure sine waves, and these modified sine waves are non-linear and high-frequency components that impair connected appliances such as fan dimmers...
