Feedback signals allow three- phase AC induction, BLDC or PMSM motors controlled with a wide variety of algorithms. The HV AC power stage includes an active interleaved power factor correction (PFC) circuit that facilitates development of PFC algorithms. An illustration of the system architecture is shown in Figure 1. The development platform consists of a controller card and the main board. The main board is not able to operate without a controller card. 2015 Freescale Semiconductor, Inc.Introduction Figure 1. High-voltage motor control development platform block diagram Warning This development tool set operates in an environment that includes dangerous voltages and rotating machinery that can result in electrical shock, fire hazard, and personal injury if not properly handled or applied. You must use this development tool with necessary caution and appropriate safeguards to avoid personal injury or property damage. Only qualified persons familiar with the risks associated with handling high voltage electrical and mechanical components, systems and subsystems can manipulate this evaluation board. You should operate this evaluation board in a lab environment only. The evaluation board is not a finished end-product fit for general consumer use. To facilitate safe operation, the input power for the high-voltage power stage should come from a current-limited laboratory power supply or isolation transformer when a power factor correction is to be investigated. If an isolation transformer is not used, the power stage grounds and oscilloscope grounds are at different potentials, unless the oscilloscope is floating. Note that probe grounds and, therefore, the case of a floated oscilloscope are subjected to dangerous voltages. You must remember that: Before moving scope probes, making connections, and such, it is generally advisable to power down the high-voltage supply. You should not touch EVM or components connected to the EVM, when these components are energized. Avoid operation in lab set-ups that have grounded tables andvchairs. You are advised to wear safety glasses, use shields, and avoid ties and jewelry and operate the development tool set only if you are trained in high-voltage lab techniques. The heat sink, power semiconductors, the PFC coils, and the motor can reach temperatures hot enough to cause burns. When powering down due to storage in the bus capacitors, dangerous voltages are present until the power-on LED is off.
