 Hello and welcome to this presentation for high-voltage solutions for motor drives. My name is Andreas Herder and I am a technical marketing manager specialized in motor control applications. This presentation will provide you with an understanding of STs, products and evaluation tools related to a 10 kilowatt motor drive. The question what is a drive sounds simple at first but the answer to that question depends on your technical expertise and level of detail you want to reach as some high-level explanations are quite straightforward while others are more complex. Let's make it simple. A drive or a variable frequency drive is an AC to AC converter. It converts electrical energy from a fixed frequency and fixed voltage into a variable frequency and variable voltage. The goal of these devices is to permanently run the motor at its optimum point across all speed and power ranges to achieve maximum efficiency for the motor and driven application thereby enabling energy savings. In this very simplified block diagram we have on the left side the AC input with fixed frequency and voltage and on the right side the variable AC output. In the center we see a few building blocks forming the main parts of the motor drive. Also there are many more building blocks to a variable frequency drive. Today I will focus on the light blue building blocks, the diode bridge, the brake IGBT, the gate drivers and the IGBT power stage. In order to briefly give an overview on the ST portfolio for power products let's divide it into three pillars. On the left side are power components that address power ranges of 10 watts to 5 kilowatts. These namely include discreet and drivers. In the center are the intelligent power modules slim. These products embed gate drivers, power transistors and protection functions in one package to address a power range between 20 watts to 3 kilowatts. On the right side you can see our ASPEC power modules. With these power modules we can address a power range from 3 kilowatts to 20 kilowatts. Let's move on to ASPEC power modules. This package is much bigger than a discreet package. The flexible pin layouts with solder pins and press fit pins and the big package size enable complex topologies in various current ratings. The ASPEC package embeds short circuit rugged IGBTs with a breakdown voltage up to 1200 volts and diodes for freewheeling and rectification depending on the topology. To ensure easy and reliable mounting screw clamps are integrated into the package. An NTC sensor is embedded in all packages for over temperature protection. The ASPEC power modules enable easy migration from discreet to module which increases power density and reduces assembly cost at the same time. Let's take a look on how these ASPEC power modules are built. The essential structure is shown on the left-hand side of this slide which is a direct bonded copper substrate, DBC at the bottom with the semiconductor dies. The DBC is connected with the high-current terminal pins then encased in a rugged plastic frame. In the center picture you see the DBC showing the mounted semiconductor dies and terminal pins. Inside the module connections are done by bond wires or traces. The DBC isolates the silicon dies from the operating environment but still providing excellent thermal conductivity for heat dissipation. Each single power pin is specified at a resistance of less than four milli ohm. There is no potting material placed within the module but the semiconductors are coated with a non-conductive gel to insulate them from the operating environment. On the right side of this slide we see the two pre-inserted screw clamps. They are attached to the plastic housing and simplify the mounting process to the heat sink. The ASPEC power modules are designed for industrial use. The qualification according to industry standards this ensures high quality and reliability. ASPEC power modules are available in two different topologies six-pack and converter-inverter break. Both packages ASPEC 1 and ASPEC 2 are UL certified. In order to evaluate ST products using our software development ecosystem we are offering evaluation boards for every product in the ST portfolio. This slide provides an overview of the evaluation board for ASPEC power modules. It features all the functions of a motor drive based on the 1200 volt 35 ampere ASPEC module with three-phase input rectifier, three-phase inverter output and a break chopper driven by the galvanic isolated gate driver STGAP 1 and controlled by a STM32F303 microcontroller. But before getting started on practical evaluations you can make comparisons using simulations created with the ST power studio tool available for free download on ST.com home page. ST power studio is a thermal electrical simulation tool for three-phase inverters for ASPEC power modules and slim IPMs. The simulation takes into account the momentary temperature dependent characteristics of the silicon which leads to very accurate results throughout the entire mission profile. The single or dual gate driver STGAP 2 can be evaluated using dedicated evaluation boards with flexible footprints for TO220 and TO247 switches in half-bridge configuration.
