STMicroelectronics introduce UPS evaluation board
 |
STMicroelectronics has introduced a line interactive 450W UPS evaluation board, the STEVAL-ISS001V2, which is built employing off-line topology with AVR boost and buck regulation of the mains. The inverter module contains the push-pull DC-DC converter and the DC-AC output full bridge generating a quasi-sine waveform. |
A microcontroller controls all UPS functions. It monitors the mains parameters (input/output mains voltage and phase, output inverter voltage, battery voltage, output current and output power) in order to ensure the proper level of the output voltage.
The UPS is designed with RS-232 joint signal and USB interfaces (USB for RS-232 converter). It is possible to connect the UPS to a PC using an RS-232 or USB cable and control the UPS status through the "UPS Monitor 3.0x" software that must be installed on the same PC.
Gerber files, schematics and bills of materials are available for the board, which uses a variety of ST devices including ST7 8-bit MCU’s, power MOSFETS and protection devices.
This 230V, 50Hz model is also available in a 120 Vac version (STEVAL-ISS001V1)
