In photovoltaic system, the characteristic of photovoltaic module such as open circuit voltage and short circuit current will be changed because of cell temperature and solar radiation. Therefore, a boost converter of the PV system connects between the output of photovoltaic system and DC link capacitor of grid connected inverter as controlling duty ratio for maximum power point tracking (MPPT). This paper shows the dynamic characteristic of the boost converter by comparing single-loop control algorithm and two-loop control algorithm using both analog and digital control. The proposed both compensation method has been verified with computer simulation and simulation results obtained demonstrate the validity of the proposed control schemes.

An electronic controller of vehicle implements a number of control form measured voltage of vehicle battery . In general, the battery voltage measurement, the voltage distribution method using a resistor circuit is used. Error of the measured battery voltage is generated due to various reasons, such as resistance error, wire resistance differences. This paper presents a method of correcting the measurement error of battery voltage of Smart Junction Block(SJB) and to minimize the voltage output control error to Vehicle exterior lamp accordingly.
