Provided is a maximum power point tracking control circuit using a sample/hold circuit. The maximum power point tracking control circuit includes a solar cell array, a sample/hold circuit, a proportional-integral controller, a buck converter, and a double pole switch. The maximum power point tracking control circuit can obtain high efficiency and tracking accuracy by using a simply designed sample/hold circuit. The sample/hold circuit includes a timer, a first multivibrator, a second multivibrator, and a hold capacitor. |
