摘要

在目前的情况下，利用废热发电已成为研究和工业部门的一个有吸引力的选择。传统的余热回收技术大多使用热电发电机(TEG)，将热能转化为电能。本文提出了一种用于热电发电系统的带开关电容电池的非隔离高升压DC-DC功率变换器。非隔离型高升压DC-DC变换器具有良好的输出稳节性，开关电容变换器具有较高的电压增益。因此，该变换器具有较高的电压增益和良好的稳压性能。此外，使用扰动和观察(P&O)和增量电导(INC)技术的最大功率点跟踪(MPPT)用于跟踪TEG的最大功率。本文采用PSIM对该带跟踪控制器的变换器进行了设计和仿真。

Performance evaluation of non-isolated high step-up DC-DC converter for thermoelectric energy harvesting system using MPPT control techniques

In the present scenario, electricity generation from waste heat has become an attractive option in both research and industrial sectors. Conventional waste heat recovering techniques mostly use ThermoElectric Generators (TEG), for conversion of heat energy into electrical energy. In this paper a non-isolated high step-up DC-DC power converter with switched capacitor cells is proposed for the ThermoElectric power generation systems. The non-isolated high step-up DC-DC converter has the advantage of good output regulation and switched capacitor converter provides a high voltage gain. Hence, the proposed converter has high voltage gain and excellent voltage regulation. Additionally, Maximum Power Point Tracking (MPPT) using the Perturb and Observe (P&O) and Incremental Conductance (INC) techniques are used to track maximum power from the TEG. This paper presents the design and simulation of the proposed converter with tracking controller using PSIM.
