Latest Patents

One of Selvaraj's latest patents is focused on an H-bridge buck-boost for adaptive driving beam headlamps. This invention describes light-emitting diode (LED) and non-LED driver systems and methods that reduce current overshoot, deadtime, and other undesirable effects in applications such as adaptive driving beam headlamp applications. These improvements positively impact circuit parameters, including efficiency. In certain embodiments, this is accomplished by using a current clamp circuit that is controlled to limit an overshoot in load current, particularly when the number of LEDs that are turned on changes.

Another significant patent involves narrow pulse widths in H-bridge buck-boost drivers. This patent describes systems and methods for generating short load current pulses using an H-bridge. In various embodiments, this is achieved by controlling, in a shunting mode, a low-side switch of the H-bridge to drive a first average current and controlling, in a non-shunting mode, a high-side switch of the H-bridge to drive a second average current. This innovative approach ensures that the first and second average currents are substantially the same, thereby reducing the current pulse width of the load current.
