Reference Designs and Associated Training Videos

PMP23069 3.6-kW single-phase totem-pole bridgeless PFC reference design with a > 180-W/in³ power density
This reference design is a GaN-based 3.6-kW single-phase continuous conduction mode (CCM) totem-pole power factor correction (PFC) converter targeting maximum power density. The power stage is followed by a small boost converter, which helps to reduce the size of the bulk capacitor. The LMG3522 top-side cooled GaN with integrated driver and protection enables higher efficiency and reduces power supply size and complexity. The F28004x or F28002x C2000™ controller is used for all the advanced controls that includes fast relay control; baby boost operation during AC dropout event; reverse-current-flow protection; and communication between the PFC and the housekeeping controller. The PFC operates at a switching frequency of 65 kHz and achieves peak efficiency of 98.7%.

TIDM-HV-1PH-DCAC Single-Phase Inverter Reference Design With Voltage Source and Grid Connected Modes
This reference design implements single-phase inverter (DC-AC) control using the C2000™ F2837xD and F28004x microcontrollers. Design supports two modes of operation for the inverter. First is the voltage source mode using an output LC filter. This control mode is typically used in uninterruptible power supplies (UPS). Second is grid connected mode with an output LCL filter, which is typically used in solar inverters. Firmware for the design is supported under the powerSUITE framework which enables adaptation using the Solution Adapter and enables tuning of the control loop using the Compensation Designer and SFRA. High-efficiency, low THD and intuitive software make this design attractive for engineers working on inverter design for UPS and alternative energy applications such as PV inverters, grid storage and micro grids.

TIDUEG2C TIDM-02002 Bidirectional CLLLC resonant dual active bridge (DAB) reference design for HEV/EV onboard charger
The CLLLC resonant DAB with bidirectional power flow capability and soft switching characteristics is an ideal candidate for Hybrid Electric Vehicle/Electric Vehicle (HEV/EV) on-board chargers and energy storage applications. This design illustrates control of this power topology using a C2000™ MCU in closed voltage and closed current-loop mode. The hardware and software available with this design help accelerate your time to market.

TIDM-02008 Bidirectional high density GaN CCM totem pole PFC using C2000™ MCU
This reference design is a 3.-kW bidirectional interleaved continuous conduction mode (CCM) totem-pole (TTPL) bridgeless power factor correction (PFC) power stage using a C2000™ real-time controller and LMG3410R070 gallium nitride (GaN) with integrated driver and protection.  This power topology is capable of bidirectional power flow (PFC and grid-tied inverter) and it uses LMG341x GaN devices, which enables higher efficiency and reduction in size of the power supply. The design supports phase shedding and adaptive dead time for efficiency improvements, input cap compensation scheme for improved power factor at light loads, and non-linear voltage loop to reduce voltage spikes under transient in PFC mode.

TIDUAI7 TIDM-BIDIR-400-12: 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 bidirectional DC-DC converter. A phase-shifted full-bridge (PSFB) with synchronous rectification controls power flow from a 400-V bus/battery to the 12-V 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 a Texas Instruments TMS320F28035 32-bit microcontroller, which is placed on the LV side. This digital 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.

TIDU638 TIDM-BUCKBOOST-BIDIR Bi-Directional Non-Isolated Buck Boost Converter
This design implements a bi-directional, non-isolated buck boost power converter, ideal for solar microconverters, hybrid electric vehicles (HEV) including Regeneration (Regen or Recuperation), and battery charging applications.

Variable-frequency, ZVS, 5-kW, GaN-based, two-phase totem-pole PFC reference design
This reference design is a high-density and high-efficiency 5-kW totem-pole power factor correction (PFC) design. The design uses a two-phase totem-pole PFC operating with variable frequency and zero voltage switching (ZVS). The control uses a new topology and improved triangular current mode (iTCM) to achieve both small size and high efficiency. The design uses a high performance processing core inside a TMS320F280049C microcontroller to maintain efficiency over a wide operating range. The PFC operates with variable frequency between 100 kHz and 800 kHz. A peak system efficiency of 99% was achieved with an open-frame power density of 120 W/in3.
