Or perhaps you werebuilding an electric fence or tryingto trigger a xenon strobe tube. Nomatter (来源：淘豆网[/p-5012941.html])what you were trying plish, you probably ran Intothe same problem every time-how to efficiently and economical-ly generate a high voltage.High-voltage technology hasnot changed much In the last cen-tury. Usually. we don't electrostatl-cally generate high voltages,except for experimental or educa-tional purposes, or by accidentwhen we pet the cat. In mostcases, we want to produce highvoltages from relatively low DC volt-'& ages or ordina(来源：淘豆网[/p-5012941.html])ry 117-volt house5!!&. current. In the case of a DC power1:; supply, the typical solution Is to cre-~ ate a DC-to-AC power inverter,andti then step up the resulting AC.~ through a tronsformer. That's often~ a very Inefficient process.w Generating a high voltage from~ an AC power source Is often event worse. In that case, alternating cur-rent must be stepped down tosome low voltage, rectified (to pro-38 vide DC),and then put through aThanks (来源：淘豆网[/p-5012941.html])to thedevelopment ofthe SIDAC,it is now easy to generate ahigh-voltage output capableofdriving neon or lase1~tubes without resorting tothe inefficimt plicated circuitconfigtwations ofthe past.DC to AC circuit. Talk about Ineffi-cient. Each conversion (or Inver-sion) decreases efficiency.The simplest way to generate ahigh voltage Is to use AC voltage asthe initial power source, which canbe stepped up via transformer.Thelatter method is reliable and e(来源：淘豆网[/p-5012941.html])ffi-cient, but requires enormous trans-formers (which strictly follow thepower factor rules) for even modestvoltage gains. Generally speaking,doubling the secondary outputvoltage requires twice the primarycurrent. A typical neon transformercan supply 10-12 kV at 30 mA anddraw almost 400 watts! The killer isthat the transformer Is likely toweigh about twenty pounds.Basic DC-to-AC Inverters. Figure 1KENTONCHUNillustrates the most boslc form ofDC-to-AC(来源：淘豆网[/p-5012941.html]) Inverter. When momen-tary switch S1 Is In Its normally openposition, no current flows In the cir-cuit. Closing S1 causes current toflow from Ihe bottery Into the pri-mary winding of Tl , generating ic field. After a short time,the current reaches Its maximumlevel and S1 Is released. The ic field In Tl collapses, producingan extremely high-voltage pulseacross Tl 's secondary winding.While the circuit In Fig. 1 Is fairlyreliable, It requires a ve(来源：淘豆网[/p-5012941.html])ry large cur-rent source and a heavy-duty trans-former when operated at lowerfrequencies . Large currentdemands result In high power fac-tors and high losses. Its greatestdrawback Is that It requires a warmbody to stand around and contlnu-ally press the button.That type of cir-cuit Is also not very energy efficient,By raising the operating frequen-cy of the circuit, It is possible to usetransformers with less Iron for thesame voltage increase. The r(来源：淘豆网[/p-5012941.html])easonthat WWII avionics ran at 400 Hzwas for exactly that reason-youcould get away with much lightertransformers.

The circuit In Fig. 2 is anexample of a basic high-frequencyDC-to-AC Inverter. Many of thehlgh-efficiency 12-volt DC to 117-volt AC power Inverters and unln-terruptlble power supply (UPS)designs use a similar configurationas the heart of the circuit.In the Fig. 2 circuit. an NE555 oscil-lator/timer (IC1) is set up as a pu(来源：淘豆网[/p-5012941.html])lsegenerator. the frequency of whichcan be set to almost any value.Theoutput of IC1 Is directed through atransformer and stepped up to therequired level. The major limitation ofthe Fig. 2 circuit Is Its output power.The NE555 can directly source up to200 mW through the transformer.butat the power-supply rail of 9 volts.that's barely enough power to lighta tiny neon lamp. Only by addingoutput switches and a higher supplycurrent can the circuit provideenough power to start a laser or aneon tUbe.An SCR-Based Inverter.
