Practical guides to high-voltage electronics, from MOSFET protection and flyback drivers to rectifiers, voltage multipliers and resistor networks.
Follow circuit diagrams and worked examples to choose components, understand capacitor discharge and explore rising-arc demonstrations.
Choose a high-voltage diode by its real circuit stresses. Compare reverse voltage, charging pulses, recovery time, SiC capacitance and cooling, with worked examples and HVE rectifier options.
Read articleSize a bleeder resistor from capacitor voltage, discharge time and stored energy. Follow worked 5 kV and 20 kV examples, including power and working-voltage limits.
Read articleLearn how a Jacob’s ladder creates a rising electric arc, why it can stall, and how voltage, current, AC/DC output and burst-driven flybacks change the display.
Read articleSee where a flyback diode goes and how it protects a MOSFET. Compare diode, TVS and RC suppression, with circuit diagrams and a worked current-decay example.
Read articleCalculate multiplier output voltage, ripple and voltage drop with a worked example, then choose the stage count, capacitors, diodes and AC driver for a useful loaded output.
Read articleCalculate a high-voltage divider’s ratio, meter loading and power dissipation. Learn why resistor working voltage, tolerance and bandwidth matter as much as resistance.
Read articleUnderstand AC and rectified DC outputs, compare single-switch, half-bridge and full-bridge drivers, and match the transformer to its winding, voltage and load requirements.
Read articleWhy one MOSFET cannot block both voltage polarities, how common-source and common-drain pairs work, and how to choose the right high-voltage switch board.
