4200V high voltage supply “The Killer”

Providing output of a kilowatt long-term and in excess of 4 kVA short-term, undoubtedly it is the most powerful single-phase power supply I’ve made, and the scariest of them all! Whether you want to power up medium size Tesla coils, arc-weld through any sensitive electronic evidence or commit suicide using one of the most horrendous ways, this beast always gets the job done.… [read more]

Triac phase regulator

This circuit, also informally known as the poor man’s variac, is used in many applications in both consumer and industrial electronics, where a perfectly sinusoidal waveform is not required and a real variac (variable autotransformer) would be too heavy and bulky. This is the case of light dimmers, vacuum cleaners, motor speed control, heater elements and similar. It was… [read more]
