Introduction

AI Translation

The EG8026 is a dedicated control IC for DC/AC inversion and PFC boost in bidirectional inverters (a single circuit that can function as both an inverter and a battery charger). It integrates two 600V half-bridge high-voltage MOS gate drivers with ±2A output current capability, and features four independent cycle-by-cycle PWM shutdown protections to effectively prevent MOS damage caused by excessive peak currents under extreme conditions. Two SD pins are also provided — SD1 and SD2 — where SD1 is the cycle-by-cycle shutdown pin for Driver 1 (HO1 and LO1), and SD2 is the cycle-by-cycle shutdown pin for Driver 2 (HO2 and LO2). Combined with external comparators, the SD function enables overcurrent and short-circuit protection.

The EG8026 consists of two main functional blocks. The first is DC/AC inversion control, which converts high-voltage DC into a pure sine wave AC output. The second is PFC boost control, which converts grid AC into high-voltage DC to supply the voltage required for battery charging.

In DC/AC inversion mode, the EG8026's core internal modules include an SPWM sine wave generator, dead-time control circuit, multi-channel feedback and protection processing circuit, and UART serial communication module. Comprehensive protection features are provided, including DC bus overvoltage and undervoltage protection, AC output undervoltage protection, overload alarm indication, overload protection indication, overcurrent protection indication, over-temperature protection indication, and short-circuit protection indication.

In PFC boost mode, the EG8026's core internal modules include a digital differential AC input voltage feedback circuit, DC output voltage feedback, differential current feedback, digital multiplier, and digital voltage-loop and current-loop controllers. Protection features include AC input undervoltage protection, output overload and overcurrent protection, and output high-voltage overvoltage protection.
