Embodiments of the present disclosure disclose a method for improving a performance of a pulsed-ultraviolet (PUV) device. The method includes monitoring an input current across a circuit breaker in communication with a UV lamp, where the input current is delivered by a power signal and is interrupted by the circuit breaker upon exceeding a predefined cut-off current； generating a pulse signal having a set of frequencies based on the power signal for driving the UV lamp, where the pulse signal is associated with a predetermined cut-off frequency that increases the input current beyond the cut-off current； determining a predefined threshold current less than the cut-off current； and configuring the pulse signal with multiple distinct pulse frequencies per second for a predefined configuration period based on the input current exceeding the threshold current. The distinct pulse frequencies per second include at least one pulse frequency greater than the cut-off frequency.
