👉 The duty fluid, often referred to as the duty cycle or duty time, is a critical parameter in the operation of duty-cycled power supplies, particularly in switching power supplies and battery chargers. It represents the fraction of time a power supply is actively delivering power to a load versus being in a standby or off-state. For instance, if a power supply operates at 80% duty cycle, it means it is actively supplying power for 80% of the total time and is in a low-power state for the remaining 20%. This concept is essential for managing energy consumption, heat dissipation, and the longevity of electronic components, ensuring efficient operation and minimizing wear and tear.
