JHL series bidirectional programmable AC power supply (BPAC)
Product Overview
The Bidirectional Programmable AC Power Supply is an advanced power electronic device that integrates bidirectional energy flow, high-precision output, and intelligent control. It can function both as a traditional AC power source providing stable voltage/current output and as an "active load" to feed energy back to the grid or energy storage systems, enabling efficient energy recycling. The product is widely used in renewable energy R&D, electric vehicle testing, industrial automation, laboratory verification, and other fields. It is an ideal solution for power electronics, energy management, and smart manufacturing scenarios.
Product Features
Bidirectional Energy Flow
Output Mode: Provides pure, stable AC power with precise programmable adjustment of voltage, frequency, and waveforms (sine wave, square wave, harmonics, etc.).
Regeneration Mode: Can efficiently feed back the electrical energy generated by tested equipment (such as inverters, batteries, energy storage systems) to the grid or storage devices, with energy saving rates exceeding 90%, significantly reducing testing costs.
High Precision and Wide-Range Adjustment
Supported voltage range: 0~300V/0~690V (customizable extension), frequency range: 0.1Hz~1000Hz, with resolution up to 0.01Hz.
Output accuracy: Voltage/current accuracy ≤0.1%, waveform distortion (THD) <1%, meeting stringent testing standards.
Intelligent Programmable Control
Built-in function generator supports transient waveform generation, voltage sag/swell simulation, harmonic injection, and other functions, adapting to complex test scenarios.
Provides multiple communication interfaces including LAN/GPIB/USB/RS485, supports SCPI commands, and can be seamlessly integrated into automated test systems.
Multi-Mode and Protection Mechanisms
Supports various working modes such as constant voltage (CV), constant current (CC), and constant power (CP), flexibly adapting to different load requirements.
Features multiple protection functions including overvoltage, overcurrent, short circuit, and overtemperature to ensure the safety of both the equipment and the device under test.
Application Scenarios
Renewable Energy Field: Grid-connected/off-grid testing of photovoltaic inverters/energy storage converters (PCS), MPPT efficiency verification.
Electric Vehicles: Charge/discharge performance testing of onboard chargers (OBC), motor drive systems, and charging piles.
Industrial Automation: Dynamic characteristic analysis of frequency converters, UPS power supplies, and power electronic devices.
Laboratory R&D: Simulation of grid disturbances, voltage fluctuations, and other extreme conditions to verify equipment reliability and compatibility.
