Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...

Active current shaping using flyback ac-to-dc converter provides power factor control and dc voltage regulation. Distributed power supplies will be the new architecture for next generation PCs and ...

A proposed new model for current-mode control retains the strengths of existing models such as ease of use and the ability to capture subharmonic oscillations, while improving on weaknesses like dc ...

Inductor-inductor-capacitor (LLC) serial resonant circuits, as shown in Figure 1, can achieve both zero voltage switching on the primary side and zero current switching on the secondary side in order ...

The MR267 current-loop controller (CLC) optional attachment remotely controls a motorized potentiometer or rotary camswitch via 4 to 20-mA current loop, 0 to 2.5-V input, or external potentiometer.

The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...
