What is a low voltage microcontroller (MCU)?
In the low-voltage domain, a microcontroller (MCU) generates pulse-width modulation (PWM) signals to the power switches. The MCU runs the sensing and speed control in a closed loop, and handles host functions to fulfill mandatory hardware and software security and safe code execution requirements.
How do I power the MCU from external 5V?
There is also a provision to power the MCU from external 5 V by populating components R7, C10, and C11 on the board. The sensed signals I_U, I_V, I_W, V_DC, and MODULE_TEMP are connected to ADC input pins after the RC filtering (for aliasing). 1V65_REF and 3V3_REF are also provided to ADCs for any ratiometric measurements.
What is a voltage source inverter?
Voltage source inverters (VSIs) are commonly used in uninterruptible power supplies (UPS) to generate a regulated AC voltage at the output. Control design of such inverter is challenging because of the unknown nature of load that can be connected to the output of the inverter.
How does a C2000 MCU control the output voltage?
To regulate the output voltage of the inverter, current and voltages must be sensed. The fast and precise on-chip analog-to-digital converters (ADCs) on the C2000 MCU are excellent to sense these signals. Sigma delta-based sensing can provide easy isolation and superior sensing of these signals.
How to control a PV micro inverter?
This section describes the details of software implementation of control of PV micro inverter. PV inverter control requires closed loop control of the DC-DC and DC-AC stage. PWM switching rates of the power stages are chosen such that only a single, fast 50-KHz ISR is needed for controlling the DC-DC flyback and the DC-AC inverter stage.
Can I use isolated power supplies on a C2000 MCU?
Use isolated power supplies. This reference design follows an HSEC control card concept, and any device for which the HSEC control card is available from the C2000 MCU product family can be potentially used on the design. The key resources used for controlling the power stage on the MCU are listed in Table 3.
