Beschreibung

This reference design illustrates a method to control a bidirectional interleaved continuous conduction mode (CCM) totem pole (TTPL) bridgeless power factor correction (PFC) power stage using a C2000™ microcontroller (MCU) and LMG3410R070. This power topology is capable of bidirectional power flow (PFC and grid-tied inverter) and it uses Gallium Nitride (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. The hardware and software available with this reference design accelerates time to market.

Eigenschaften

  • Interleaved 3.3-KW Single Phase Bridgeless CCM Totem Pole PFC Stage
  • 100-kHz Pulse Width Modulation (PWM) Switching
  • Programmable Output Voltage, 380-V DC Output Nominal
  • Less Than 2% Total Harmonic Distortion (THD)
  • Greater Than 98% Peak Efficiency
  • powerSUITE™ Support for Easy Adaptation ofDesign for User Requirement
  • Software Frequency Response Analyzer (SFRA) for Quick Measurement of Open Loop Gain
  • Soft Starting of PWM for Reduced Zero Current Spike in TTPL PFC

Typische Anwendungen

  • HVAC motor control
  • Merchant network & server PSU
  • DC charging (pile) station / Wireless EV charging station
