Photovoltaic DC-DC converters are a crucial part of PV power conversion. The DC-DC converter is provided to regulate the constant output under various operating conditions of photovoltaic cells. Bourns offers large portfolio of high voltage circuit protection and circuit conditioning (Magnetic) devices to meet the needs of PV DC-DC designers.
The dc-dc converter topology used for the PV based micro-inverter is given in Fig. 1. It comprises of a conventional boost converter and two separate dc capacitors. Here the input-side capacitor and inductor are given by Cin and Lin respectively.
The major issue of solar PV modules is low supply voltage which is increased by introducing the wide input voltage DC-DC converter. The merits of this introduced converter are low-level voltage stress on diodes, good quality supply power, high voltage gain, plus low implementation cost.
Therefore, a DC-DC converter employing some MPPT algorithm is generally used as a front-end converter to efficiently extract the PV output power and convert the PV output voltage to a high voltage DC-BUS. Depending on the system requirement, the DC-DC converter can use either an isolated power stage or a nonisolated stage.
The single-phase PV based grid-tied micro-inverter system is shown in Fig. 1. It consists of two power processing stages. The dc-dc stage comprises an isolated boost dc-dc converter topology which produces a dc-link voltage for the VSI. This converter not only extracts the maximum power from the PV panel but also step-up the low input voltage.
This paper is devoted to the modelling and control for a low cost, high-power quality single-phase voltage source inverter (VSI) for a grid-tied PV-based micro-inverter system. The first stage includes a high-efficiency isolated boost dual half-bridge dc-dc converter topology which interfaces to the PV panel and produces a dc-link voltage.
