The correctness and feasibility for the bidirectional LLC converter topology under the proposed charging and discharging control strategy of the DC bus are verified by simulation and experimental results. 1. Introduction

Are bidirectional power conversion blocks a solution to energy storage challenges?

A potential solution to these challenges is bidirectional functionality for AC/DC, DC/AC and DC/DC power-conversion stages. To further increase system integration, system BOM and form-factor reductions, the landscape of grid systems that involve energy storage is moving toward bidirectional power conversion blocks like those shown in Figure 2.

What is a photovoltaic energy storage complementary system?

A single-phase, two-stage photovoltaic energy storage complementary system is shown in Figure 1, where the system consists of solar panels, boost converters, bidirectional DC/DC converters, battery packs, inverters, relays, etc. There are two significant features in the system.

What is a bidirectional DC/DC converter?

Moreover, the bidirectional DC/DC converter is adopted as the energy storage conversion module in the photovoltaic energy storage complementary system; it has the feature of bidirectional power flow and plays the role of regulating power, recovering energy, and maintaining the stability of the power supply.
