12VDC to 220-380VDC Converter

When powering many appliances from a sine wave inverter, the HV DC is converted to AC only to be rectified back to DC in the appliance. This inverter eliminates the SPWM stage and outputs DC only. This DC can be used to power appliances, or as a HV DC source for your SPWM, variable...
