6 FAQs about [51 MCU controls photovoltaic panels]

How a PV panel voltage is controlled by a control loop?

Under this control scheme, when the PV panel voltage tends to go higher than the reference panel voltage set by the MPPT algorithm, the control loop increases the panel current command (reference current for inner current loop Iind_ref) and thereby controls the panel voltage at its reference level (Vpv_ref).

How many channels can a photovoltaic system control?

Likewise, results confirm that the proposed photovoltaic system able to control over 4400 channels instead of traditional techniques. Therefore, proposed photovoltaic system based on FPGA allows controlling a huge number of channels and bringing huge amount of power.

How does an MCU control a power supply?

The MCU controls the hardware using three feedback signals and four PWM outputs. The signals that are sensed and fed back to the MCU include the Vpv, the boost output voltage (Vboost), and the total boost inductor currents (Iind). These sensed signals implement the voltage and current control loops for the DC-DC boost stage.

What is an overvoltage protection (OVP) in MPPT DC-DC EVM?

A mechanism for an overvoltage protection (OVP) is implemented in the software for this MPPT DC-DC EVM. This OVP applies only for the boost output and not for the LLC stage output. Since the Piccolo controller is on the primary side of the isolation, the controller has no knowledge of the isolated LLC output.

How does the MCU control the hardware?

The MCU controls the hardware using three feedback signals and two PWM outputs, PWM3A and PWM3B. The feedback signals include the panel output voltage (Vpv), the flyback input current (Ipv), and the flyback output voltage (Vbus).

What is MPP in photovoltaic panels?

This MPP represents the optimum operating point at which the panel operates at its maximum power. However, the photovoltaic energy produced is highly dependent on the irradiance, the temperature and load, which impacts the position of the MPP variable over time.
