Description
- The Microtek V8 Model PCB (Printed Circuit Board) is the main control board used in certain Microtek Square Wave or Hybrid inverters, typically in the 900VA to 1100VA capacity range. It serves as the “brain” of the inverter, managing the core functions of power conversion, charging, and protection.
- Key Components and Functions
- The V8 PCB features a robust design composed of several critical functional blocks:
- Microcontroller Unit (MCU) / Micro IC:
- This is the central processing unit, often a Surface-Mount Device (SMD) IC (e.g., specific EBHB-SGP or XPV2-SGC series).
- Function: It is pre-programmed to control all inverter operations, including:
- Generating the PWM (Pulse Width Modulation) pulses that drive the MOSFETs for DC-to-AC conversion.
- Monitoring battery voltage, mains voltage, and output load.
- Implementing protection features (Overload, Short Circuit, Low Battery, Over-temperature).
- Controlling the battery charging process (constant current/constant voltage stages).
- Managing the display (LED/LCD indicators).
- Power / Drive Circuits:
- This section includes MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) which are typically mounted on a heat sink and are the primary switching components.
- Function: They are responsible for switching the high DC battery voltage into an AC waveform (square wave or modified square wave) using the signals from the MCU.
- Driver ICs/Transistors: Small signal transistors or dedicated driver ICs are used to boost the low-power pulses from the MCU to a level sufficient to drive the gates of the powerful MOSFETs.
- Charging Circuitry:
- Includes components like relays, diodes, and sensing resistors.
- Function: Manages the process of charging the external battery when the mains supply is present. The MCU regulates the charging current and voltage based on the battery’s state.
- Sensing and Feedback Circuits:
- Consists of a network of resistors, capacitors, and comparators.
- Function: These circuits continuously sense key parameters:
- Mains Sense: Checks for the presence and voltage of the utility power.
- Current Sense: Measures the current drawn from the battery (in inverter mode) and the charging current (in mains mode) to detect overload/short circuit and control charging.
- Voltage Sense: Monitors battery voltage and output voltage.
- Protection Circuits:
- Function: Automatically shut down the inverter or switch to a protective state when faults like overload, short circuit, low battery, or high temperature are detected, protecting both the inverter and the connected appliances
