DYNAMIC PULSE WIDTH CONTROL SCHEME IN AMPLIFIERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18088091 titled 'DYNAMIC PULSE WIDTH CONTROL SCHEME IN AMPLIFIERS
The abstract describes a patent application for amplifiers and components that adjust the OFF-pulse widths of a high-duty cycle pulse width modulated (PWM) output signal and the ON-pulse widths of a low-duty cycle PWM output signal using high-side (HS) and low-side (LS) detectors.
- HS detector detects when the gate-to-source voltage (Vgs) of the HS transistor drops below a threshold and adjusts the OFF-pulse widths of the high-duty cycle PWM output signal.
- LS detector detects when the Vgs of the LS transistor drops below the threshold and adjusts the ON-pulse widths of the low-duty cycle PWM output signal.
Potential Applications: - Power electronics - Motor control systems - LED lighting systems
Problems Solved: - Precise control of pulse widths in PWM signals - Efficient power management in electronic devices
Benefits: - Improved performance in power electronics - Enhanced energy efficiency - Greater control over electronic systems
Commercial Applications: Title: "Advanced Pulse Width Modulation Technology for Power Electronics" This technology can be used in industries such as automotive, renewable energy, and consumer electronics for more efficient power management and control.
Questions about the technology: 1. How does this technology improve energy efficiency in electronic devices? - This technology optimizes the pulse widths of PWM signals, reducing power consumption and improving overall energy efficiency. 2. What are the potential applications of this technology in the automotive industry? - This technology can be used in electric vehicles for precise motor control and energy management.
Original Abstract Submitted
Examples of amplifiers and components thereof are configured to adjust the OFF-pulse widths of a high-duty cycle pulse width modulated (PWM) output signal and the ON-pulse widths of a low-duty cycle PWM output signal. Such control is carried out using high- and low-side (HS and LS) detectors. The HS detector coupled to the control terminal of an HS transistor detects when the gate-to-source voltage (Vgs) of the HS transistor drops below a threshold and outputs an HS detection signal to adjust the OFF-pulse widths of the high-duty cycle PWM output signal. An LS detector coupled to the control terminal of an LS transistor detects when the Vgs of the LS transistor drops below the threshold and outputs a LS detection signal to adjust the ON-pulse widths of the low-duty cycle PWM output signal.
