<p>A DC-AC inverter that is adaptable for use with different input voltages and for use with different loads. The DC-AC inverter has a voltage-step-up network, with the step-up voltage set by a controller that drives totem-pole configured FET switches at a duty cycle that depends on the desired step-up voltage. The controller beneficially regulates its duty cycle in response to current and/or voltage feedback signals. Also beneficially, the DC-AC inverter includes a configurable inductor and a configurable transformer. Such configurable components enable efficient operation with different loads. Such DC-AC inverters are particularly useful in driving liquid crystal display lamps.</p> |
