Class-B or Type-B Chopper – Introduction and Operation

Introduction: Class-B or Type-B chopper is defined as the chopper in which the direction of power flow is always from load to source. The operation of this chopper is confined in the second quadrant. This is the reason; it is also known as Second Quadrant Chopper. In second quadrant chopper, the output voltage is positive … Read more Class-B or Type-B Chopper – Introduction and Operation

What is Quadrant Operation of Chopper?

The quadrant operation of chopper is basically the circuit configuration so adjusted to achieve the chopper voltage Vo and output current Io in all the four quadrants. A chopper can be operated in all four quadrants by employing required circuit configuration.   We know that, a chopper is a semiconductor power electronic device. Again, a … Read more What is Quadrant Operation of Chopper?
