Keywords:power semiconductor devices? Dual In Line-Smart Power Module? variable speed motor drives?

The terms energy-saving and quiet-running are becoming very important in the world of variable speed motor drives. For low-power motor control, there are increasing demands for compactness, built in control and lower overall-cost. An important consideration, in justifying the use of inverters in these applications, is to optimize the total-cost-performance ratio of the overall drive system. In other words the systems have to be less noisy, more efficient, smaller and lighter, more advanced in function and more accurate in control with a very low cost.

In order to meet these needs Fairchild has developed a new series of compact high-functionality and high efficiency power semiconductor device called "DIP-SPM (Dual In Line - Smart Power Module). DIP SPM-based inverters are now considered an attractive alternative to conventional discrete-based inverters for low-power motor drives, specifically for appliances such as washing machines, air-conditioners, refrigerators water pumps etc.

DIP-SPM combines optimized circuit protection and drive matched to the IGBT's switching characteristics. System reliability is further enhanced by the integrated under-voltage protection function and short circuit protection function The high-speed built in HVIC provides an opto-coupler-less IGBT gate driving capability that further reduces the overall size of the inverter system design. Additionally the incorporated HVIC allows the use of a single-supply drive topology without negative bias.

The objective of this application note is to show the details of DIP-SPM power circuit design and its application to DIP-SPM users. This document provides design examples that should enable motor drive design engineers to create efficient optimized designs with shortened design cycles by employing Fairchild DIP-SPM products.
