Abstract
Methods and apparatus controlling a wireless power transmitter by applying a first low-side driver signal to a first channel in a first pair of channels and applying a first high-side driver signal to a second channel in first pair of channels, wherein each driver signal has a state that is 'active' or 'inactive' and drives a transistor gate of a switching element. The state of each driver signal on each channel can be monitored to detect an error condition to prevent damaging current flow condition to the switching elements. When the error condition is detected, at least one of the driver signals may be set to “inactive” for a period of time.
