Phase-Shifted Quad-Input LLC Converter with Variable Pulse Width Modulation1
2021 IEEE 12th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2021In this paper, a novel quad input DC-DC converter is proposed for photovoltaic (PV) applications where four PV panels are connected to the load through a single LLC tank. This topology uses Frequency Switching Modulation (FSM) to regulate the load and Phase Shift Modulation (PSM) to balance the power between both sides of the converter.

Small-signal modeling of combined phase shift and pulse width uniformly sampled modulators
2015 IEEE 16th Workshop on Control and Modeling for Power Electronics (COMPEL), 2015Multi-variable digital controllers exploiting a combination of phase shift and pulse width modulation (PSM+PWM) have recently been investigated as methods for simultaneously achieving output voltage regulation and efficiency optimization in dc-dc Series Resonant Converters. This paper discusses the small-signal dynamics of such combined phase shift and

A digital pulse-width modulator for phase-shift operation of full-bridge isolated DC-DC converters
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010This paper presents the concept, implementation and testing of a digital pulse-width modulator for phase-shift driving of full-bridge isolated DC-DC converters. The proposed phase-shift digital modulator employs a hybrid counter/delay line structure in order to achieve a 1.25 ns phase-shift resolution with a switching frequency of about 400 kHz on the ...

The Modular Multilevel Converter (MMC) topology is getting popularized for the medium to high voltage applications after its inception. This paper presents a modified topology of the conventional MMC, named as Hybrid MMC (HMMC). This topology has reduced number of switch counts than the conventional MMC.

In this paper, closed-loop control of isolated bidirectional dual-active bridge (DAB) DC-DC converter is proposed for dual-phase-shift (DPS) scheme using fixed frequency pulse-width-modulation (PWM) plus transmitted command power. DPS is a well-known control scheme to reduce backflow power, current stress, and losses, it also provides better power ...

Model predictive current control (MPCC) is a promising candidate for modular multilevel converters (MMCs) due to its advantages of direct modeling and quick dynamic response. However, the conventional MPCC experiences high load current and circulating current tracking errors since only one switching state is selected and applied during one control ...

Improved Phase-shift Pulse-width Modulation Full-bridge Converter using a Blocking Capacitor
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2011This paper presents an improved phase-shift pulse-width modulation (PWM) full-bridge converter using a blocking capacitor. As the proposed converter reduces the circulation energy by inserting only one series blocking capacitor at the primary side of the conventional phase-shift PWM full-bridge converter structure, it improves the operation ...
