PV DC/DC Converter

Our photovoltaic (PV) DC/DC converter adopts a non-isolated Buck-Boost circuit and controls the fast turn-on/turn-off of semiconductor switching devices through a high-speed DSP digital control chip. The DC voltage can be outputted from the conversion circuit. It provides preconditions for the AC inverter operation and ensures the stable high-voltage DC power output with a wide range of DC input voltage.

 

Product Naming

For example: the model of Titans 60KW non-isolated PV DC/DC module with a DC bus voltage of 750V is TDC-F60/750G-A.
