POWER MODULES Product Overview & Applications

2

A functional circuit providing a variety of commonly used power control & switching functions in a single package.

This eliminates the need for:

• Integration• Additional assembly

• Selection • Design

What is a Power Module?

3

Power Modules – also referred to as,

• Thyristor / SCR / Diode / Module• Power Block• Bridge Rectifier• Power Cube• PACE- Pak (passivated assembled

circuit elements)

Glossary of TermsAnode- An SCR terminal, positive in respect to the gate and the cathode when conducting.

Cathode- An SCR terminal, negative in respect to the anode when conducting.

Discrete Device- An individual electrical component packaged or unpackaged, such as a resistor, capacitor, transistor, diode, etc.

Diode- A two terminal semiconductor which allows electric current to flow easily in one direction but not in the other.

Heat sink- A material with good heat conducting or dissipating properties.

5

Rectifier - Same as diode. Also used to describe equipment that converts AC to DC.

Trigger - To turn on an SCR by utilizing its gate terminal.

Thyristor - A term for the general class of semiconductor devices which includes SCR’s, triacs, alternistors, etc.

SCR - Silicon Controlled Rectifier. A three terminal semiconductor manufactured from silicon that blocks current flow in one direction, can be switched from blocking to conduction in the other direction.
