HeNe Laser Power Supply (Aaron Cake) - If you have ever worked
with lasers, you know how fun and interesting it can be, you also know how
expensive it can be. The high voltage power supplies for the laser tubes are
often more expensive then the tubes themselves..... [Design by Aaron Cake] |

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) [Site is under construction

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 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.... |
|
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 High Current Power Supply (Aaron Cake) - A while ago I came up
with the idea of using a microwave transformer as a high voltage, high current power
supply. Even though I had no use for such a supply, I decided to design one anyway.
This is a very simple design. Note: I have not built this supply becasue I have no use
for it. If you build this supply without knowledge in electronics or high voltage, you
have basically signed your own death certificate. This supply can be very
dangerous if not treated properly.... [Circuit designed by Aaron Cake] |

High Voltage Low Current Supply - A high voltage power supply is a very
useful source which can be effectively used in many applications like biasing of
gas-discharge tubes and radiation detectors etc. Such a power supply could also be
used for protection of property by electric charging of fences. Here the current
requirement is of the order of a few microamps(added 10/05) |

High-Voltage amplifier drives piezo tubes - 7-Dec-04 Issue of EDN
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 by

High-Voltage Capacitors, build your own! - As one who supplies parts to
those who experiment with high voltage, I get a lot of letters and phone calls from
frustrated builders that go like: "Can you supply an inexpensive xxx microfarad
capacitor at a working voltage of YYY? My only source wants $249 for one."
Sometimes, a high price is justified; other times, a seller has the only capacitors of
a special value available, and will soak you for the maximum dollar.…. [Tony van
