The DIAC is an abbreviation for Diode AC semiconductor switch. The prefix ‘Di’ indicates, that the device has two terminals like […]

The auxiliary voltage commutation is also called as “Impulse commutation”, or class D commutation. The circuit diagram for class D

Load in Parallel with the SCR The class A commutation is also called as self commutation. Fig. 1 shows the

Semiconductor Fuse is a power device required to be protected against large currents. The semiconductor fuse is the fast-acting fuse

Before we go into the circuit details of CSI we must know the difference between a VSI and a CSI.

In this topic, you study the Difference Between Voltage Source Inverter (VSI) and Current Source Inverter (CSI).

The transient overvoltages can switch on the thyristor. In some cases, the thyristor can be damaged due to these transient

The online UPS is also called inverter preferred UPS. Block Diagram & Working of Online UPS Fig. 1 shows the

The offline UPS is also called line preferred UPS. Block Diagram of Offline UPS Fig. 1 shows the block diagram
