VSG Control for Cascaded Three-Phase Bridge Based Battery Inverter
With the increasing number of new energy sources connected to the grid, the unbalanced output of three-phase grid-connected inverters and the lack of no inertia and damping characteristics in the traditional microgrid control system will seriously affect

Speed control with low armature loss for very small sensorless brushed DC motors [PDF]
A method for speed control of brushed dc motors is presented. It is particularly applicable to motors with armatures of less than 1 cm3. Motors with very small armatures are difficult to control using the usual pulsewidth-modulation (PWM) approach and ...

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

Interleaved Pulse Width Modulation Based on Modified Carrier in Parallel Operation
An interleaved pulse width modulation (PWM) can be employed in a parallel operation of three-phase converters because the interleaved PWM increases the equivalent switching frequency and significantly enhances the output current harmonics.

A Soft-Switching Control for Cascaded Buck-Boost Converters Without Zero-Crossing Detection
This paper proposes a novel soft-switching control without zero-crossing detection for the cascaded buck-boost converters (CBBCs). The proposed soft-switching control consists of two parts: soft-switching modulation and closed-loop control.
