  • Using AC PWM Drives on Non-Standard Voltages and Frequencies

    Often, there may arise the need to apply an AC PWM drive1 to input voltages such as 200, 208, 380, 415 and possibly other levels, as well as input frequencies such as 50 Hz. The AC PWM regulator utilizes a switching power supply for control power that is sourced from a DC bus. This gives the unit

  • The lowdown on lowdropout regulators

    powering the microprocessor for a simple reason. The amount of voltage available to power the primary system limits the size of the possible overhead. Most embedded applications get power from either high-voltage multiphase or low-voltage single-phase sources. The ac voltage is transformed

  • Technical Article: Double Conversion Electronic Voltage Regulator Operation

    The double conversion electronic voltage regulator differs significantly in operation from the tap switching type EVR. The double conversion EVR uses a rectifier to convert AC power to DC and then uses an inverter to convert the DC power back to AC. Voltage regulation is obtained in one of two ways

  • Technical Article: Automatic Voltage Regulator Phases and Phase Regulation

    Automatic voltage regulators can be designed for single phase or three phase AC applications. It is common for utilities to use single phase automatic voltage regulators ganged together to provide voltage regulation for three phase. These are often "can-type" units pole-mounted outdoors. Single

Discussions about AC Voltage Regulator Schematic
  • Re: Regulator Circuit

    By "one phase" do you mean one side of a center-tapped secondary transformer? By "all phases" do you mean both ends of a center tapped secondary transformer? Are you attempting to feed the 7805 directly from the transformer or do you have a rectifier, such as a full wave or full wave bridge rectifie...

    Hi everybody, I've been busy these days and I apologize for being late. Today I've been working on the project and I wish to share with you my findings: 1.As first, friend of mine brought the book that you have recommended. It is good to have it.The first ten pages have good hints about generators...

  • Re: Controlled Saturable Reactors in Power Supplies

    Somewhat off topic, but your question brings to mind a battery charger/power supply I have, built by La Marche back in 1972 or so, that has two transformers, one of which is labeled a "saturable transformer" on the schematic. It is wired in series with the main power transformer, and supplies volta...

  • Re: Faulty Power Supply

    It's sounds like you've popped the voltage regulator. Imagine that there is a voltage regulator chip, or circuit, in there that gets 40V as an input and outputs a variable voltage. If the voltage regulator dies, then the raw 40V input will be on the output. I would take it apart and see what sort...

  • Re: low voltage from 12volt inverter/charger

    Well do you see that IC labeled U14 on the schematic? That's the charge regulating chip. You need to take your oscilloscope and read the duty cycle of the signal going to the charging transistor. Oh, you probably should first look at the AC to DC power supply stage of the charger circuitry and dete...

    In USA and Canada, the system voltage is 480V AC for3 phase system and 240V AC for single phase system, How is it possible, since the line to neutral voltage is 480/root3=277, then how it become 240V

  • Convert AC to DC

    Hey gents, I have this problem of converting 240V AC to 28V DC. I know the traditional way of using step down transformer then rectifier bridge then voltage regulator and what not. However the transformer is required to be mounted on the PCB (rating at 100VA, 3A --> too big) so this traditional

  • Seiko Instruments Releases the Innovative S-19500/19501 Series LDO Voltage Regulator with Watchdog Timer and Reset Function for Automotive Applications

    CHIBA, Japan--(BUSINESS WIRE)--Seiko Instruments Inc. (SII) announced the release of the S-19500/19501 series LDO voltage regulator with an easily-controlled watchdog timer and reset function that simplifies implementation. The new regulators are optimized for use in constant-voltage power supply for automotive electric components and microcontroller monitoring. Traditionally, external monitoring has been required for microcontroller safety, and it has complicated circuit designs and increased

  • OFGEM report reaffirms risks for fixed voltage reduction equipment

    In its latest Electricity Capacity Assessment Report, the industry regulator OFGEM has reaffirmed that the National Grid may have to reduce the voltage of its supply network in the event of a severe reduction in capacity margins. The measure would be implemented if the new balancing services announced by OFGEM failed to reduce the demand sufficiently. Although a reduction in voltage would not cause problems for most users, for example causing the lights to dim, it would have major implications for companies that have installed fixed voltage reduction equipment to save energy. "With fixed voltage reduction, a drop in the supply voltage can have serious consequences for susceptible electrical equipment," according to Martin Ward, managing director of Claude Lyons. "However, this is not an issue with automatic mains voltage stabilisers, which always keep their output at the desired level." Voltage reduction devices are frequently used by industry to save costs and energy. They are particularly effective in the UK, since although the UK mains voltage is a nominal 230 V, in practice it is typically above 240 V, which is unnecessarily high for equipment designed for continental European markets. For many types of equipment this leads to a waste of power and can reduce equipment lifetimes. Claude Lyons is a leading manufacturer of automatic mains voltage stabilisers, which provide a constant output voltage irrespective of supply voltage or load. Claude Lyons Energy Saving Stabilisers incorporate a motorised variable transformer, which combined with a sensor unit, ensures the output is held at the specified value. They are sometimes referred to as mains voltage regulators or line conditioners. -ends- Image captions Image 1.
