A Safety Enhanced, High Step-Up DC-DC Converter for AC Photovoltaic Module Application
Tsorng-Juu Liang

Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious growth. However, a high voltage gain converter is essential for the module's grid connection through a dc-ac inverter. This paper proposes a converter that employs a floating active switch to isolate energy from the PV panel when the ac module is off; this particular design protects installers and users from …
