Switch driver for power device reliability improvement
The patent US12074509B2 describes an innovative apparatus designed to enhance the control of switch circuits through a sophisticated switch driver circuit. The apparatus includes a switch circuit with a first terminal, a second terminal, and a control terminal, alongside a sensor that measures the voltage magnitude between the two terminals. The switch driver circuit is responsible for receiving a pulse width modulation (PWM) signal from a controller and the voltage magnitude from the sensor. It then applies a driving pulse to the control terminal, with the current magnitude of the pulse being determined by the measured voltage. The claims further elaborate on the capability of the switch driver circuit to adjust driving pulse parameters based on various operational modes and additional sensor inputs, which may include voltage, temperature, or current sensors.
Additionally, the patent outlines methods for implementing the described apparatus, emphasizing the dynamic adjustment of driving pulses based on voltage thresholds and operational modes. The switch driver circuit can operate in different modes, such as soft switching or hard switching, and can modify the driving pulse strength within defined limits. The system is particularly applicable in configurations involving multiple photovoltaic panels, where each power device integrates the described switch circuit and driver. This design aims to optimize the performance and efficiency of power devices by allowing for real-time adjustments based on sensor feedback and operational conditions, thereby enhancing the overall functionality of photovoltaic systems.
