HVAC equipment manufacturers build units that can be applied with various voltages. Some applications utilize an input or supply voltage of 277-1-60. This power supply comes from a 460-3-60 (4-wire) ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...

The widespread usage of powerful energy accumulators (batteries and supercapacitors) is leading to improvements in current management. A bidirectional DC/DC converter can prolong the battery’s life ...
