This paper proposes a front end integrated dual output (IDO) dc-dc converter for commutation torque ripple reduction in a permanent magnet brushless DC (BLDC) motor drive. The current ripple owed to the inductance and resistance of the motor during commutation instant results in torque ripple. In this work the dc link voltage of the converter is varied at commutation instants to minimize current ripple and hence torque ripple. The wider output range and faster response of the IDO converter make it a suitable choice as a front end converter for minimizing torque ripple.Simulation results validate the proposed converter for the BLDC motor drive. Experimental analysis of a conventional drive is performed to verify the simulation results.

“…To construct a multi-port system, employing multiple conventional single-input single-output (SISO) dc-dc converters is a feasible solution, but undesired high cost and large volume are incurred due to the large number of components. Actually, components such as magnetic elements and semiconductor devices in different power electronics converters can be multiplexed to achieve reduced cost, which have been adopted to derive a variety of integrated multi-port converters in [9][10][11][12][13][14][15][16][17][18].…”

“…Besides of the magnetic elements, semiconductor devices can also be multiplexed. In [16][17][18], integrated three-port dc-dc converters with reduced switches/diodes are proposed, in which only three switches/diodes instead of four are utilized to generate the required two control variables for independent power control and voltage regulation. Therefore, not only low cost is obtained, but also no cross-regulation problem exists.…”

Thanks to the favorable advantage of low cost, integrated three-port dc-dc converters with reduced switches have attracted extensive attention. In order to provide more new topologies, this paper aims to propose a programmable topology derivation method, which effectively simplifies the cumbersome process of the conventional combination method. Instead of the manual connection and examination, the proposed alternative can quickly and rigorously derive multiple viable integrated three-port dc-dc topologies from a great number of possible connections with the aid of computer program. Besides, generalized analysis is also accomplished, with which performance characteristics of all derived converters are simultaneously obtained and then a comprehensive comparison can be easily conducted to select a preferred one for the practical application. Finally, an example specific application with one input and two outputs is given, with topology selection, design and experimental results demonstrated in detail.

“…The secondary side post regulators (SSPR) have been proposed to tightly regulate the output voltage with small output voltage error. They can regulate each output voltage independently, however, additional switches, gate driving circuits, and voltage controllers are required [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

A dual-output LLC resonant converter using pulse frequency modulation (PFM) and asymmetrical pulse width modulation (APWM) can achieve tight output voltage regulation, high power density, and high cost-effectiveness. However, an improper resonant tank design cannot achieve tight cross regulation of the dual-output channels at the worst-case load conditions. In addition, proper magnetizing inductance is required to achieve zero voltage switching (ZVS) of the power MOSFETs in the LLC resonant converter. In this paper, voltage gain of modulation methods and steady state operations are analyzed to implement the hybrid control method. In addition, the operation of the hybrid control algorithm is analyzed to achieve tight cross regulation performance. From this analysis, the design methodology of the resonant tank and the magnetizing inductance are proposed to compensate the output error of both outputs and to achieve ZVS over the entire load range. The cross regulation performance is verified with simulation and experimental results using a 190 W prototype converter.
