Abstract
Methods and circuits are provided for controlling an electronic switch such that it may be controlled by an external control signal, such as a PWM signal, or be set to operate in an active-diode mode, wherein current is allowed to flow through the switch in only one direction. The described circuits are configured to autonomously control the electronic switch, such that no external control signal is required when the active-diode mode is used. The provided techniques allow electronic switches to be efficiently used as part of a power stage or part of an active rectifier, so as to support bi-directional switched-mode power supplies, motor/generator drivers, and related electric circuits that require bi-directional power flow. By reusing electronic switches thusly and implementing an active-diode mode, the circuitry is minimized while maintaining good power efficiency.
