Current transformer energy harvesting reference design with supercapacitor for fault indicator lights

Power management for the energy harvesting, energy buffering and back-up power is a key challenge in the fault indicator design. The TIDA-01385 introduces a circuit about harvesting energy from a current transformer for the system load of a fault indicator while storing the extra energy in a super capacitor. A primary Li/SOCl2 battery is used as back-up power to extend the fault indicator operating time after the power grid fails. With input current from 3mA to 2A, the reference design provides a stable 3.6V to system load within two seconds.

Bidirectional 400V-12V DC/DC converter reference design

The Bidirectional 400V-12V DC/DC Converter Reference Design implements an isolated bidirectional DC/DC converter based on a microcontroller. The phase-shifted full bridge (PSFB) with synchronous rectification controls the power flow from the 400V bus/battery to the 12V battery in buck mode, while the push-pull stage controls the reverse power flow from the low-voltage battery to the high-voltage bus/battery in boost mode. . This implementation uses a Texas Instruments (TI) 32-bit microcontroller TMS320F28035 on the low-voltage side to achieve closed-loop control of bidirectional power flow. This digital controller system implements advanced control strategies to optimally control power stages under varying conditions and provides system-level intelligence for safe and seamless transitions between operating and PWM switching modes.

Bidirectional 400-V/12-V DC/DC Converter Reference Design

The Bidirectional 400V-12V DC/DC Converter Reference Design is a microcontroller-based implementation of an isolated bi-directional DC-DC converter.  A phase shifted full-bridge (PSFB) with synchronous rectification controls power flow from a 400V bus/battery to the 12V battery in step-down mode, while a push-pull stage controls the reverse power flow from the low voltage battery to the high voltage bus/battery in boost mode.  In this implementation closed loop control for both directions of power flow is implemented using Texas Instruments 32-bit microcontroller TMS320F28035, which is placed on the LV side. This digitally-controller system can implement advanced control strategies to optimally control the power stage under different conditions and also provide system level intelligence to make safe and seamless transitions between operation modes and PWM switching patterns.
