Practical Aspects in Building Three-Phase Power Converters
Published in Dorin O. Neacsu, Switching Power Converters, 2017
For low-power applications, the parasitic inductance of the IGBT package and mounting on the bus bar are smaller than the inductance of the DC link. This is the case of discrete IGBTs or IGBT-based power modules used in applications above tens of amperes. Using power modules is definitely better as all connections are inside the package with extremely low parasitic inductances. The common solution consists of a simple decoupling capacitor across the entire inverter leg, providing a noninductive path for current transition (Figure 6.10a). High-frequency polypropylene film capacitors or other low equivalent series inductance-capacitors are especially designed for dual module IGBTs. They are mounted directly on the module terminals (Table 6.2) [8,9].

This module is the dual module of interaction with throwboxes present on board user nodes and implements two dual procedures, store and get, plus a take procedure. This module is also in charge of interworking with the DSS by leveraging features provided by the DSS modules. In what follows we will refer to the practical case of a DSS implemented in the form of a DHT. store(content-id)→ result: it is used to store into the DHT the content; the indexing is performed by means of the identifier content-id and the result of the operation is returned (e.g., success, alreadypresent when another content with the same content-id exists, DHT-failure); get(query)→ content-id/ exception: it requests to the DHT module to retrieve from the DHT the content indexed with the identifier query;if the content is not available, it returns an exception (e.g., content not yet/no more available); take(query)→ content-id/exception:same as get but the data corresponding to the identifier query is removed from the DHT.

Firstly, the effectiveness of the boost function of ADP5092 with one TEG module and two TEG modules in series is tested. The heater temperature is set at 50, 60, and 70°C for one TEG module, and 90, 100, and 110°C for two TEG modules in series. The experimental result is given in Table 1. It is clear that the boosted output of the ADP5092 reaches its specified value (around 3.4 V) when the input of the ADP5092, namely the VOC, is more than 426 mV, regardless of single-module TEG or dual-module TEG in series is used as the power supply.
