If anet connects a driver cell of lower voltage to a sink cell of higher voltage, its route includes a level converter
(LC) and is decomposed into two segments of low and high supply voltages, corresponding to before and after the LC.
Besides the socket for MCU there is integrated voltage regulator 7805 to obtain 5V for powering the kit, level converter
MAX232 for connecting the TTL logic levels of the MCU serial interface to the serial port on PC; then 2 LEDs and 2 push switches to allow some inputs/outputs for the MCU.
A microcontroller implements the user interface via an RS-232 level converter
Whenever the irradiance is below the required level converter
will boost up the power generated from the panel by means of this function.
Presented grid connected modular converter consist of 3 CHB per phase resulting in 7 voltage level converter
. The basic converter scheme is shown in Fig.1.
3 (Ozen, 2005) consists of an 8-bit microcontroller unit, which is an 8051 derivative, with CAN controller and flash, and a RS232 level converter
. The firmware detects the protocol that the vehicle uses for the OBD-2 communication.
Second "extension board" provides user interface parts like buttons LCD screen and also extension components for mainboard like external EEPROM memory and RS232 level converter
for PC communication support.
