310W PSU Using Transition Mode Bridgeless PFC and LLC-SRC - Reference Design
PMP9640: High efficiency, high power factor and reliable power supply are the main focus of the PMP9640 design for motor driver applications. Low cost analog transition mode (TM) PFC controller UCC28051 has been used for bridgeless PFC as the first conversion stage of the PMP9640. LLC series resonant converter (SRC) with UCC25600 is applied as the second stage of the PMP9640. In addition, a high-side buck converter with UCC28710 is applied here as the bias supply. In this design, bridgeless PFC efficiency can go up to 98.5%.
Automotive 60W Brushless DC (BLDC) Motor Drive
TIDA-00143: This TIDA-00143 reference design is a BLDC motor controller and is designed to operate from a single 12V (nominal) power supply which can vary over a wide range of voltages as found in typical automotive applications. The board is designed to drive motors in the 60W range, which require currents of 5 Amps. The size and layout of the board is intended to facilitate evaluation of the drive electronics and firmware, with easy access to key signals on individual test points. Connection to a wide variety of motors is possible using either the 3-contact connector or by soldering motor phase wires to plated-through holes in the board. The 12Vdc power is fused to prevent damage to the board or to bench power supplies in case of a motor fault during testing. Command and status of the motor can be communicated through the standard JTAG connector, or through PWM input and output signals. Users can also re-program the microcontroller through the JTAG connector, allowing customization to a wide variety of applications.
