  • Efficient AC
    at the same time. This phenomenon reduces ac network capacity, in essence aggravating any energy problems on the power grid. So to head off the problem, electronic motion controls of this type must use an input section that incorporates a power-factor correction circuit. Bridgeless operation
  • AC Motors
    A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary (rotor
  • Interfacing to AC Power Lines
    CIRCUIT ON I/O. Microchip Technology Inc. PINS. VDD. INTRODUCTION. This application note describes a simple method for. P. measuring parameters from the AC power line. Parameters such as zero crossing, frequency, and. I/O pin. relative phase can be measured. This method is useful. N. for measurements
  • PROPER WIRING PRACTICES FOR AC and DC DRIVES
    installing AC and DC Drives. KB ELECTRONICS, INC. "The Right Control. 12095 NW 39th Street, Coral Springs, Florida 33065 USA. for your Application". (954) 346-4900 FAX (954) 346-3377. SUBJECT: PROPER WIRING PRACTICES FOR AC and DC DRIVES. The subject of electrical noise (Radio Frequency Interference
  • Dimming AC Incandescent Lamps Using A PIC10F200
    One of the earliest circuits in home electronics is the venerable incandescent AC lamp dimmer. It is also one of the most challenging circuits to get right. In this technical brief we will examine how using a microcontroller can both simplify the circuit and make it efficient. Early dimmers were
  • Solid-State ac Power Sources for Transformer Testing
    are giving way to automated test facilities using solid-state ac-power sources with computerized controls that offer near instantaneous change over test parameters. A single automated test set can replace a wide range of test equipment including applied test sets, induced step-up transformers, core loss
  • Combing GDTs and MOVs for Surge Protection of AC Power Lines (.pdf)
    reference is IEEE C62.41-1991 entitled "IEEE Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits" (formerly IEEE Standard 587).This standard defines the open circuit voltage and short circuit current waveforms which can be expected to occur on AC power lines of 1000 Volts (RMS
  • Teccor Thyristors used as AC Static Switches and Relays (.pdf)
    types of applications are described in detail in "Phase Control Using Thyristors" (AN1003). The circuit shown in Figure AN1007.1 provides random (anywhere in half-cycle), fast turn-on (<10 µs) of AC power loads and is ideal for applications with a high-duty cycle. It eliminates completely the contact
