Our team has spent six months cooperating closely with our valued client to jointly develop a brand-new inverter control board. We encountered countless tough challenges throughout the whole process, including unstable sampling signals and mismatched PWM driving parameters. Both sides held regular technical meetings, repeatedly adjusted circuit layouts and optimized protection logic day after day. After numerous rounds of prototype testing, troubleshooting and performance calibration, we finally achieved fully qualified stable performance. This successful product not only meets strict electrical parameter standards but also passes all temperature and overload reliability tests, marking a precious milestone of our long-term technical partners.
Inverter board parameters
Main Electrical Parameters of Inverter Control Board
1. Power Supply Parameters (Board Self-Power)
1. Input auxiliary voltage: DC 12V / 24V / 36V / 48V
2. Working current: 80mA ~ 300mA
3. Standby power consumption: ≤1W
4. Operating voltage tolerance: ±15%
An inverter control board is the core circuit motherboard of an inverter device. It sends operation instructions, collects real-time data, adjusts power output, and protects the whole inverter from faults. It acts as the "brain" of inverters (solar inverters, motor inverters, UPS inverters).
2. Core Main Functions
1. Signal Sampling & Detection Collect voltage, current, temperature, frequency signals from DC input, AC output and power modules. 2. PWM Pulse Generation Output adjustable PWM signals to drive power IGBT/MOSFET switches, convert DC to stable AC power. 3. Closed-loop Operation Control Automatically adjust output voltage/frequency to match load demands; maintain stable power waveform.
4. Multi-layer Safety Protection Trigger alarm or shutdown when overvoltage, overcurrent, overheating, short circuit, overload occur.
5. Communication & Human Interaction Connect with display screens, Bluetooth, RS485, WiFi; upload running data to monitoring systems; show fault codes.
3. Main Key Components on the Board • Main control chip (MCU/DSP): Central computing unit • PWM drive optocouplers: Isolate and transmit driving signals
