  • 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
  • Incompatibility of Power Factor Correction Capacitors with AC PWM Drives
    factor as seen by the user's line. A bank of these oil-filled or dry type AC capacitors usually reside in a conspicuously placed metal enclosure nearby the motor. Beware of retrofitting any AC controllers (including VVI and CSI types) to existing induction motors! If the installation is not thoroughly
  • Braking and Regenerative Energy with AC Drives
    someplace. In the case of an AC PWM drive, that someplace is back to the DC bus (The DC bus is that portion of the drive after the rectifier section where DC power is collected and stored for use by the inverter section).
  • Controlling 3-Phase AC Induction Motors Using the PIC18F4431
    the load. To drive an AC induction motor, the 3-phase inverter. FIGURE 2: OPEN-LOOP V/f CONTROL. bridge is driven by a microcontroller's PWM outputs, as. BLOCK DIAGRAM. shown in Figure 2. By changing the PWM duty cycles. in a regular manner, the PWM outputs are modulated. Speed. to synthesize
  • Measuring Linear and Non-Linear AC Waveforms with CurrentWatch (.pdf)
    Variable frequency drives (VFDs) improve control and conserve energy by regulating motor speed. The most. common types are PWM (pulse width modulation) and Six Step. Both technologies are based on high speed switching, which distorts the AC sine wave and can make accurate current sensing difficult.
  • Understanding Electronic Motor Drives
    magnitude voltage pulses. All PWM drives contain an input converter, dc bus, and output inverter. For simplicity, only one phase of input and output are shown for a 3-phase drive. Selecting the right drive is essential to getting the best performance and efficiency from an electric motor. A motor
  • Brushless Sine Drives
    . Galil currently offers two sine drives. The AMP-43640 is a 20W x 4 axis linear amplifier. with a current loop bandwidth of up to 7 kHz. The larger 600W x 4 axis AMP-43540 is a. fully digital PWM sine drive that has a 33 kHz PWM frequency, which allows for a. closed-loop current bandwidth of up to 4
  • Jog Circuit for the SP500 Drive: Setup and Configuration
    The success of the SP500 as an AC PWM drive can largely be attributed to its ease of set-up and configuration. Unlike the newer AC drives, however, neither the keypad nor the terminal board offered a dedicated jog PB. Should the need arise, jog functionality can be achieved by the methods discussed
