This paper presents a maximum power point tracking (MPPT) circuit composed of analog circuits suitable for solar cars. The MPPT controller circuit, which consists of analog switches and two op‐amps achieved precise MPPT during solar power generation. This MPPT controller circuit was constructed using a small number of CMOS elements, and the circuit of the step‐up DC‐DC converter achieved a conversion efficiency higher than 98% as well as weight reduction. Eighteen of the proposed MPPT circuits were installed (in serial and in parallel) in a solar car called “2013 Tokai Challenger” at an international competition, and it was shown that it could generate sufficient power supply from solar power.

具有模拟控制的MPPT电路，适用于太阳能汽车

本文提出了由适用于太阳能汽车的模拟电路组成的最大功率点跟踪（MPPT）电路。由模拟开关和两个运算放大器组成的MPPT控制器电路在太阳能发电过程中实现了精确的MPPT。这种MPPT控制器电路是使用少量CMOS元件构成的，升压DC-DC转换器的电路实现了高于98％的转换效率并减轻了重量。在一次国际比赛中，有18个建议的MPPT电路（串联和并联）安装在称为“ 2013 Tokai Challenger”的太阳能汽车中，结果表明它可以产生足够的太阳能电力。
