The high voltage AC power board HVPB-A has an input voltage of AC 90V – 260V and delivers a maximum of 2.5A DC current to BLDC motor. It should be connected to the evaluation board FOC-EVB to work with the Holtek BLDC Motor Workshop development platform. The BLDC Motor Workshop delivers the convenience of development and realizes a complete solution from evaluation, development to production.
The HVPB-A board embeds the highly integrated motor driver SIM6822M, and provides functions such as shunt current sensing, bus voltage sensing, over current protection. Note that the power input must be isolated by a set of isolation transformers to maintain safety.
