Abstract
A boost converter, a method of converting power and a power supply incorporating the boost converter or the method. In one embodiment, the boost converter has an input couplable to a source of electrical power and includes: (1) a boost inductor coupled to the input and adapted to conduct currents bidirectionally, (2) a first controllable switch coupled to the boost inductor, (3) a second controllable switch coupled to a node between the first controllable switch and the boost inductor and (4) a controller, coupled to the first and second controllable switches, that closes the first controllable switch to provide a charging conductive path across the input to charge the boost inductor and alternately closes the second controllable switch to provide: (4,) a forward conductive path from the boost inductor to an output of the boost converter when a voltage at the node exceeds a voltage at the output to provide power to the output and (4,) a reverse conductive path from the output to the boost inductor when the voltage at the output exceeds the voltage at the node to decrease the voltage at the node and thereby decrease a switching voltage of the first controllable switch.
