Abstract
The present invention discloses a dimming circuit with a load capacity adjustment mechanism and method thereof. The dimming circuit includes a control module, a waveform switching module, a filtering module and an amplification module. The control module generates a pulse-width modulation (PWM) signal. The waveform switching module inverts the pulse-width modulation signal to generate a first conversion signal, and then inverts the first conversion signal to generate a second conversion signal. The waveform of the first conversion signal is opposite to the waveform of the PWM signal, and the waveform of the second conversion signal is the same as the waveform of the PWM signal. The filtering module filters the second conversion signal to generate a filtered signal. The amplification module processes the filtered signal to generate a dimming signal.
