摘要： The invention comprises: a smart junction box with a safe mode for photovoltaic solar power modules; and the related method of operation. Power MOSFETs are used as active bypass diodes during the normal operation of the smart junction box, but in safe mode the power MOSFETs are turned on continuously, thereby reducing the output voltage to a safe level of approximately 200 mV. A Non Volatile Memory (NVM) keeps the module in the safe mode after power from the PV cells is interrupted by momentary shading or night. The smart junction box includes transmitter and receiver circuits for wirelessly communicating with other smart junction boxes. The smart junction box enters safe mode in response to receiving a shut-down signal, and exits safe mode in response to receiving a restart signal. The smart junction box acts as a signal repeater, thereby ensuring that the shut-down and restart signals propagate to all junction boxes in the solar array. Some embodiments of the smart junction box include at least one detection circuit for detecting the interruption of current flowing through the junction box, and the receiver circuit typically interprets the detected interruption of current as a shut-down signal.

摘要： A solar power module, and related method of operation, that protects the bypass diodes in the solar power module from overheating due to partial shading, and also protects firefighters and installer personnel from electrical shock hazard. The solar power module includes active bypass switches, and isolation switches that disconnect the PV cells from the bypass switches when all the bypass switches are closed concurrently, thereby allowing the PV cells to continue supplying power to the control circuitry. The isolation switches are also used to maintain the solar power module in a safe state during installation, or in case of fire.

摘要： A smart junction box for a photovoltaic solar power module, and related method of operation. The junction box includes a plurality of active bypass circuits for protecting the solar cells from reverse bias, a novel power supply circuit in several embodiments that can operate with input voltages of either positive or negative polarity, a capacitor for storing and supplying energy, and a master control circuit. The master control circuit is able to enable/disable the power supply, force the bypass switches to open, and modulate the on-resistance of the bypass switches. The master control circuit performs these functions in a coordinated way to maintain the voltage across the capacitor within predetermined limits, thereby ensuring the internal circuitry is powered under all operating conditions including: full sunlight, partial shading, full shading, and safe mode for reducing the risk of electrical shock to firefighters.

摘要： The active rectifier circuit and related method of operation disclosed herein is self-powered and improves the efficiency and reliability of photovoltaic solar power systems by replacing the conventional bypass and blocking rectifiers used in such systems. The circuit includes a power MOSFET used as a switch between the anode and cathode terminals, and control circuitry that turns on the MOSFET when the anode voltage is greater than the cathode voltage. The method of operation utilizes resonance to produce a large periodic voltage waveform from the small anode-to-cathode dc voltage drop, and then converts the period voltage waveform to a dc voltage to drive the gate of the power MOSFET.
