Minimum off time control systems and methods for switching power converters in discontinuous conduction mode |
摘要 |
Systems and methods are provided for managing switching operation of a power converter, for example and without limitation, for powering LEDs in an efficient manner. According to one aspect, a system for managing a switching operation of a power converter includes an off time control system for managing operation modes of a power converter. The off time control system includes an active device for transmitting a bias signal, where the bias signal is configured for modulating a zero diode current signal for controlling a trigger signal, and a resistive body for discharging the bias signal. |
