What is VFD Drive Circuit: Its Operation, Types and Applications

VFD is the short form of a Variable Frequency Drive or adjustable frequency drive. The frequency determines the motor RPM and by controlling the AC frequency the motor RPM can be controlled. Different types of VFDs are available in the electronics and electrical market ranging from small motor related applications to the high power induction motors. Other than the three-phase VFDs, single phase VFDs are also available.

7.4V Two Step Lithium Battery Charger Circuit – CC and CV mode

The advancement in Electric Vehicles, Drone and other mobile electronics like IoT Devices seems to be promising for the future. One common thing among all these is that they are all powered by batteries. Following Moore’s law the electronic devices tend to become smaller and more potable, these portable devices should have their own source of power to operate. The most common battery choice for portable electronics today is Lithium Ion or Lithium Polymer Batteries. While these Batteries have a very good charge density they are chemically unstable under harsh conditions hence care should be taken while charging them and using them.

Soft Start Circuit for Power Supply

Soft Start Circuit for Power Supply

A Soft Start Circuit prevents the sudden current flow in the circuit during the start. It slows down the rate of rising output voltage by minimizing the excess current flow during the start. It is useful to protect the devices or electronic components from the damage caused by instantaneous high input current. Some components which are current limited and having poor load regulation can get damaged because of this high input current. Here we are building the soft start circuit using a voltage regulator IC LM317 and a PNP transistor BC557.

Flyback Converter Circuit

Flyback Converter Circuit

In electronics, a regulator is a device or mechanism which can regulate the power output constantly. There are different kinds of regulators available in the power supply domain. But mainly, in the case of DC to DC conversion, there are two types of regulators available: Linear or Switching.

Instrumentation Amplifier Circuit using Op-Amp

Instrumentation Amplifier Circuit using Op-Amp

Almost all types of sensors and transducers convert real world parameters like light, temperature, weight etc into voltage values for our electronic systems to understand it. The variation in this voltage level will help us in analyzing/measuring the real world parameters, but in some applications like biomedical sensors this variation is very small (low-level signals) and it is very important to keep track of even the minute variation to get reliable data. In these applications an Instrumentation Amplifier is used.

DIY Waveform Generator using Arduino​

DIY Waveform Generator using Arduino​

Every Engineer who loves to tinker with electronics at some point of time would want to have their own lab set-up. A Multimeter, Clamp meter, Oscilloscope, LCR Meter, Function Generator, Dual mode power supply and an Auto transformer are the bare minimum equipments for a decent lab set-up. While all of these can be purchased, we can also easily built few on our own like the Function Generator and the Dual mode power supply.

DIY Coil Gun

DIY Coil Gun

The basic principle behind a Coil Gun is that a current carrying conductor will induce a magnetic field around it, which was stated by Faraday. To improve the strength of this magnetic field the current carrying conductor is wound in form of a coil. Now, when this coil is powered it produces a magnetic field around it which is strong enough to attract metal (or other Ferro magnetic) pieces a.k.a projectiles into it.
