An inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor. Without an inverter, the AC motor would operate at full speed as soon as the power supply was turned ON. You would not be able to control the speed, making the applications for the motor limited.
The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.
The network of Power Transistors of a small Inverter drive is actually one ‘Intelligent Power Module’ (known as an IPM) and includes its own protection and basic control circuits. The IPM inverts the DC into AC - hence the term ‘Inverter’. The control method is known as ‘PWM’ for 'Pulse Width Modulation'.
A 250-W isolated micro inverter design presents all the necessary PV inverter functions using the Piccolo-B (F28035) control card. This document describes the power stages on the micro inverter board, as well as an incremental build level system that builds the software by verifying open loop operation and closed loop operation.
All of the key functions are implemented on the F28035 MCU for the Solar Micro Inverter kit. A C2000 piccolo microcontroller with its on-chip PWM, ADC, and analog comparator modules can implement complete digital control of a micro inverter system. Figure 4 shows a simplified diagram of different stages present on the Solar Micro Inverter kit.
The AC source cannot take reverse power flow, therefore do not increase the inv_Iset such that the micro inverter board feeds power into the AC source, as this can damage the AC power supply. The maximum value for the setup described above is around 0.2 pu.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%.
