    Accuracy? Resolution? Arc minutes? How to take charge of your motor control design

    Imagine your commute this morning in your car. The traffic light turned green, and you pushed the accelerator as soon as you could. Your car responded within seconds and you continued on toward the office. But behind the scenes, inside your car, there was a lot more happening. Let’s take a look. When you press the pedal, the motor does its...

    How to reduce system cost in a three-phase IGBT-based inverter design

    Most three-phase inverters use insulated gate bipolar transistors (IGBTs) in applications like variable-frequency drives , uninterruptible power supplies, solar inverters and other similar inverter applications. Each phase of a three-phase inverter uses a high- and low-side IGBT to apply an alternating positive and negative voltage to the motor coils...

    How to minimize MOSFET conduction loss in battery-powered motor drives

    Many applications use low voltage battery (2-10 cell lithium-ion) powered motor drives like power tools , garden tools and vacuum cleaners . These tools use brushed or brushless DC motors (BLDC). BLDC motors are more efficient and have less maintenance, low noise and longer life spans. The most important performance requirements of the power stage...

    How to detect insulation failures in electrical equipment – part 2

    In my last post , I emphasized the importance of insulation in electrical equipment. In this post, I will describe another method to measure the leakage current through the insulation resistance. Figure 1 is a high-level block diagram of this method, which entails applying a fixed voltage (500V, generated using a high-voltage DC/DC converter on a...

    Accelerate to higher performance

    Engineers designing real-time control systems are constantly faced with the challenge of optimizing performance. These systems require minimal latency where the time delay between sampling, processing, and outputting must fit within a tight time window in order to meet the performance specifications. At the heart of the control systems are math intensive...

    How to detect insulation failures in electrical equipment – part 1

    Insulation deterioration is one of the primary causes of electrical-equipment failure in motors, high-voltage transformers and generators. Insulation failure can cause dangerous voltages, fires, high-fault currents and explosions, damage to equipment and property, personal injury, and fatal accidents. The main causes of insulation failure are dielectric...
