The F28379D is capable of generating very complex PWM gating signals. Trying to make sense of it all can require extreme mental gymnastics. PSIM's code generation tools will help simplify this process so that you can easily simulate and move to the hardware stage with confidence.
THIS WEBINAR COVERS HOW TO:
- Use PWM waveforms to trigger other PWM waveforms with different logic settings
- Trigger a PWM from an analog current feedback using the onboard comparators
- Setup slope compensation for peak current control
To accomplish the above topics THESE SPECIFIC FEATURES ARE BEING USED and set up using PSIM embedded code generation:
- X-BAR
- Trip zone settings
- Multiple trip sources
- Using trip sources to set a PWM high, low, toggle, etc. on the carrier rising or falling slopes.
- Comparator initialization
- Setup slope compensation for peak current control
Code is being generated and the operation verified with a real-time Hardware-in-the-Loop simulation using a Typhoon HIL600 and a TI F2879D controlCARD.
OTHER HIGHLIGHTS:
- A bi-directional phase-shifted full-bridge converter with peak current mode control and an active secondary controlled by the HIL simulation with real control hardware and code.
- The forward direction features peak current control from the DC input current. The DC input current toggles the phase-shift to transfer more or less power to the secondary. This phase-shifted waveform is then being mapped to the X-BAR to generated the active rectifier waveforms.
- In the reverse direction, the secondary side is controlled with a phase-shifted constant duty cycle which is then mapped to the X-Bar again to generate new gating waveforms for the full-bridge circuit.
If none of this makes sense, GOOD, watch the webinar recording and then then it will make sense.
