DSPIC33EP512MC806-I

The Microchip dsPICDEM™ MCHV-2 Development Board aids in the rapid evaluation and development of a wide variety of high-voltage motor control applications. This development board is targeted to control Brushless DC (BLDC) motors, Permanent Magnet Synchronous Motors (PMSM), and AC Induction Motors (ACIM) in both sensored or sensorless operation. The MCHV-2 can be configured to use with Microchip’s motor control dsPIC Digital Signal Controllers (DSCs), supporting 100-pin Plug-in Modules (PIMs) for the dsPIC33F, E and C motor control devices. There is also an option to mount a 28-pin SOIC dsPIC33 DSC device directly. The development board uses a three-phase Integrated Power Module device (IPM) that contains the motor inverter and the gate driver’s circuitry. The circuit drives 3-phase motors using different control techniques without requiring any additional hardware. The MCHV-2 supports using either the internal op amps found on dsPIC33E and dsPIC33C motor control DSCs, or the external op amps found on the MCHV-2 board for current sensing.<p>The rated continuous output current from the inverter is 6.5A (RMS). This allows up to approximately 2 kVA output when running from a 208V to 230V single-phase input voltage in a maximum 30ºC (85ºF) ambient temperature environment. Therefore, the development board is ideally suited for running a standard 3-phase AC Induction Motor of up to 1.4 kW (1.8 HP) rating or a slightly higher rated industrial servo-motor. The IPM is capable of driving other types of motors and electrical loads that do not exceed the maximum power limit and are predominantly inductive. Furthermore, single-phase loads can be driven using one or two of the inverter outputs. The unit is capable of operating from 85VAC up to a maximum of 265VAC.<p>The MCHV-2 (DM330023-2) replaces and is fully backwards compatible with the previous MCHV (DM330023) and all motor control PIMs.

With the common use of cards instead of cash, Credit Card Reader (MSR, mag stripe/swipe readers) are an essential part of any POS system. MSRs can read any card with magnetic stripes, including some driver's licenses, gift cards, and other IDs.<p>Magnetic Card Readers (also known as Magnetic Stripe Readers or MSRs) read data from a 3-track magnetic stripe via a peak detection circuit and process that data for downstream users. After extracting data from the magnetic stripe, it is converted to binary data and formatted for encryption. They feed the swiped information to applications management software and connect through USB, RS-232, or PS/2 connections.<p>Microchip Magnetic card reader solution reads ISO/IEC-7811 cards (also known as “Frequency/double Frequency” (F2F) encoding standard). The data format encodes 7-bit data on Track1, 5-bit data for Track 2 and 3. Please refer to the features section for an in depth description of the Magnetic card readers capabilities.<p>Microchip offers 2 solutions, one using the dsPIC33EP family and the other using the PIC24F family of PIC's<p>This demo is not for sale, but can be easily created from components listed in the user's guide.<p>For questions related to this board please contact http://www.microchip.com/support

The 50W Interleaved LLC Converter Development Board is a generic development board implementing interleaved LLC topology supporting rapid prototyping and code development based on dsPIC33 DSCs. It utilizes the dsPIC33CH128MP506 DSC supporting a fully digital and advanced power control algorithm scheme. The board is compatible with dsPIC33EP, dsPIC33CK and dsPIC33CH Digital Power Plug-in Modules (DP-PIM).

Microchip’s 200W DC/DC LLC Resonant Converter Reference Design operates over a wide input voltage range (350 - 420Vdc) with a nominal input of 400V, providing a 12V DC output, while maintaining high-voltage isolation between the primary and secondary. High efficiency is achieved through Zero Voltage Switching (ZVS) on the half-bridge converter and Zero Current Switching (ZCS) on the synchronous rectifier. A synchronous rectifier is implemented over the traditional full wave rectifier for improved efficiency. The DC/DC LLC Resonant Converter Reference Design utilizes Microchip’s digital power conversion dsPIC for unique “adaptive” control of the half-bridge converter and synchronous rectifier.<p>This reference design is implemented using a single dsPIC33EP / dsPIC33FJ “GS” digital-power DSCs from Microchip that provides the full digital control of the power conversion and system management functions. As shown in this reference design the efficient use of dsPIC33EP / dsPIC33FJ ‘GS’ devices enable designers to easily and cost effectively create products using advanced switching techniques such as LLC that lower switching losses and enable efficiencies as high as 95%. The DC/DC LLC Resonant Converter Reference Design is royalty free when used in accordance with the licensing agreement.<p>Both the design packages (EP and FJ) are available to download under documents and software section.
