High & Low Voltage Cut Off With Time Delay - The power line fluctuations and
cut-offs cause damages to electrical appliances connected to the line. It is more
serious in the case of domestic appliances like fridge and air conditioners. If a
fridge is operated on low voltage, excessive current flows through the motor, which
heats up, and get damaged.….(electronic schematic added 08/08) |

High Current LM317 Regulated Power Supply - The high current regulator below uses
an additional winding or a separate transformer to supply power for the LM317
regulator so that the pass transistors can operate closer to saturation and improve
efficiency. For good efficiency the voltage at the collectors of the two parallel
2N3055 pass transistors should be close to the output voltage. ….(design added 11/08) |

High Current Power Supply - Since my page was first posted, I have received a
number of emails asking about a high current power supply. I looked around, but
couldn't find one that was suitable. So, I designed this. It is a linear supply, which
might have a few of you rolling your eyes, but it takes very few parts, is simple to
build and can supply huge currents. ….(electronic schematic added 11/08) |

High voltage Amplifier Drives piezo tubes - 12/07/04 EDN-Design Ideas:
Piezoelectric tubular positioners that drive manipulators in scanning tunneling
microscopes require high-voltage, low-current drive circuits. The circuit in Figure 1
can drive high-resistance, low-capacitance piezoelectric loads at a -3-dB bandwidth of
6 kHz. It offers a low-cost alternative to commercial drivers.....(design idea added

High Voltage Amplifier uses simplified circuit - 10/14/04 EDN-Design Ideas: Many
scientific instruments and sensors need ac high-voltage drive. High-voltage drive is
useful for driving electrodes in many applications. The challenge is to boost the
output of a conventional op amp to high voltages. Available ac high-voltage amplifier
modules are limited to approximately 1200V p-p.....(design idea added 5/05) |

High Voltage Breakdown Tester - (Not for beginners!) The following circuit
is used to determine the breakdown voltage of electronic components without causing
permanent damage. The circuit quickly ramps the high voltage up from zero and stops
when the leakage current reaches a preset amount up to 100 uA. When power is
applied the two-transistor flasher circuit drives the
complimentary-symmetry....(electronic circuit added 7/03) |

High Voltage Generator (Charles Wenzel ) - The simple circuit can be used at very
low frequencies, RF frequencies, low voltages, or even very high voltages with careful
selection of transistors. The power handling capability and power consumption are also
easily modified to suit the requirement.....(added 7/03) |
|
High voltage generator (Domenico Di Mario) - Easy to build, this high voltage
generator is capable of generating up to 50KV but the breakdown voltage of the coil
limits the voltage to a value somewhat lower. T2 is the ignition coil of a car and
also the 0.5µF capacitor comes from the same place: actually I suggest using only this
type of capacitor....(schematic / circuit added 05/05) |

High Voltage Regulator is 100% surface mountable - 11/24/99 EDN-Design Ideas: It
can be difficult to generatea high-voltage supply from a medium-voltage input,
especially if you need a surface-mount design. It is difficult to find surface-mount
components with the necessary specs, especially the transformer and power switches.
High-voltage surface-mount capacitors can also be hard to locate. The
