Power-Shedding Technique Increases LightLoad Efficiency Download White Paper 531Ko

The new Westcor MicroPAC takes has a factory selectable “power shedding” mode for managing parallel arrays of power modules in an intermediate bus power-distribution system. This mode optimizes efficiency across loads better than conventional approaches commonly used to boost power supply efficiency, such as pulse skipping or low-power “standby supplies.”

This month, Trinamic Motion Control is offering you to win one of four TMCM-1043 development kits for its highly integrated, NEMA 17-compatible TMCM-1043 stepDancer stepper motor module.

Offering designers an easy-to-use PC-based GUI that allows one-click modification of motor drive current, micro-stepping and other key parameters, the intuitive kits are custom designed and developed for direct mounting on a NEMA 17 motor. Pre-programmed and pre-configured with all operating parameters to support standard 1.5A (peak) motors, the TMCM-1043 board uses Trinamic´s single-axis TMC2660 stepper motor driver IC, which integrates a motor pre-driver and power MOSFETs.
