12VDC to 220-380VDC Converter
https://www.electronics-lab.com/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 frequency […]
NCH6300HV high voltage DC-DC power booster for nixie displays
https://www.electronics-lab.com/nch6300hv-high-voltage-dc-dc-power-booster-for-nixie-displays/
Nixie tube is an electronic device for displaying numerals or other information using glow discharge. A potential difference is applied between two electrodes in a glass tube containing low-pressure gas. The flow of electric current through the gas makes plasma. This phenomenon is called glow discharge. First introduced in 1955, the Nixie displays are legendary. […]
Flash Graphene Synthesis – Electricity Turns Garbage into Graphene
https://www.electronics-lab.com/flash-graphene-synthesis-electricity-turns-garbage-into-graphene/
Graphene is the thinnest yet one of the most strong materials known to man while being only one atom thick. On top of that, graphene is an excellent conductor of heat and electricity and has remarkable light absorption abilities. It is truly a material that could change the world, with unlimited potential for integration in […]
HV Nixie DC-DC Switching Power Supply using MAX1771
https://www.electronics-lab.com/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 MAX1771 Step-Up DC-DC Controller. The […]
A Cost-efficient Super-Cascode SiC Switch
https://www.electronics-lab.com/cost-efficient-super-cascode-sic-switch/
Coping with rapid technological advances and finding efficient energy solutions are the keys for development of power electronics of the future. A new research had been done in North Carolina State University about increasing the efficiency of high-power switches. Silicon Carbide is a compound of silicon and carbon with chemical formula SiC. It is a wide […]

This SMPS can be powered with low input voltage, from 5 VDC to 15 VDC and provided adjustable Output Voltage: + 92 Vdc to +340 Vdc. Can be used too, as power supply, for the Xenon Lamp, Nixie tube Clock, VFD display, Magic Eye, Neon, and too many others electronics circuits who need HV power […]
9V to 1kV DC/DC converter
https://www.electronics-lab.com/9v-to-1kv-dcdc-converter/
Bob tipped us with his latest project, it’s a 9V to 1kV DC-DC converter using CD4011 IC to produce a square wave and a IRF530 transistor to drive the transformer. Finally, I have made a new high voltage supply based on an inverter transformer and voltage doubler. It seems to be ok for this job, […]
Teardown & Repair of a Stanford Research PS350 5000V, 25W High Voltage Power Supply
https://www.electronics-lab.com/teardown-repair-of-a-stanford-research-ps350-5000v-25w-high-voltage-power-supply/
In this episode Shahriar repairs a Stanford Research Systems Model PS350 5000V-25W High Voltage Power Supply. The unit continuously displays 2.5kV without the output being enabled and produces no output voltage. Verification of power supply voltages reveals the issue is linked to a disconnected 15V voltage regulator IC. After the repair, the output voltage is […]
