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...

HV Nixie DC-DC Switching Power Supply using MAX1771

Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed. Here we designed a simple DC-DC switching regulator capable of powering most of Nixie tubes. The board accepts 12Vdc input and gives an output of 150-250Vdc. The module is based on the...
