Definitions
- the present invention has its main field of application in the industry for the design of electronic devices and, more particularly, for those conceived within the sector of power systems for photovoltaic solar energy conversion.
- the invention could also be applicable in other fields such as wind generation, power generation by electrochemical cells or other devices that provide continuous energy.
- the object of the invention is to extend the working voltage range in the switching devices in order to increase the power of the electronic DC / AC converter that conditions the energy produced by the photovoltaic panels and injects it into the power grid by improving the cost and increased the efficiency of the photovoltaic installation.
- the photovoltaic installations of network connection are formed by a set of photovoltaic panels (also called photovoltaic generator) and an electronic DC / AC converter (hereinafter converter), also called inverter, which conditions the energy produced by the photovoltaic panels and it injects it into the mains, where DC is direct current and AC alternating current.
- a set of photovoltaic panels also called photovoltaic generator
- an electronic DC / AC converter also called inverter
- In fig. 1a represents what is meant by DC voltage V C c of a converter for connection to single-phase alternating voltage V C A of the prior art.
- In fig. 1 b represents what is meant by DC voltage in a converter for alternating connection V C A three-phase of the state of the art.
- the DC voltage V C c and the voltage of the photovoltaic panel will be the same.
- the DC voltage and the voltage of the photovoltaic panel will be different.
- the value of the minimum continuous voltage is determined by the conversion structure of the converter used and by the value of the alternating voltage (that is, voltage of the electricity grid in photovoltaic installations connected to the network).
- the value of the maximum DC voltage that the converter can withstand is determined by the characteristics of the components used in the converter, usually the most critical elements being the capacitor used to stabilize the DC voltage and the devices switching (eg transistors and / or diodes).
- MOSFETs metal-oxide-semiconductor field effect transistor / Metal-oxide-field-effect transistor semiconductor
- IGBTs Insulated Gate Bipolar Transistor bipolar transistor
- Photovoltaic installations require converters with a wide DC voltage range that allows working in the range between the maximum power point voltage (Vmpp) of the photovoltaic generator at maximum ambient temperature, and the open circuit voltage (Voc) at minimum room temperature.
- Vmpp maximum power point voltage
- Voc open circuit voltage
- the value of these voltages will depend on the configuration of photovoltaic panels used (number of panels in series), the ambient temperature and their technology.
- the converter can be connected to higher voltage networks, increasing the power of the converter, making the price of the photovoltaic system better profitable by delivering more power to the network with the same hardware.
- the maximum continuous voltage limit of a typical photovoltaic installation is set at 1000 V due to the insulation levels of the photovoltaic panels. These DC voltage levels could damage the converters with 1200 V transistor switching devices with traditional switching techniques, since the overvoltages caused during the transistor switching due to the parasitic inductances (especially during the shutdown of the transistor) may exceed the limit of 1200 V.
- the converters are formed from elementary switching cells, formed by a DC voltage stabilization capacitor C, two transistors T1 and T2 in series and an output inductance L connected at the midpoint of junction of transistors T1 and T2.
- Said figure 2 also shows the parasitic inductances L3 and L4 between the capacitor C and the transistors T1 and T2, and the internal parasitic inductances L1 and L2 of the transistors T1 and T2, which depend on their manufacture.
- the parasitic inductances L3 and L4 should be reduced as much as possible in the design phase, because during the switching on and off of transistors T1 and T2 the strong current variations in said parasitic inductances L3 and L4 cause overvoltages in transistors T1 and T2 .
- the state of the transistors: on / off is controlled by the door-emitter voltage.
- the control of this tension is done through of a controlled voltage source or driver D1 and D2 (hereinafter, voltage source) and a gate resistor Rg1 and Rg2 connected between each voltage source D1 and D2 and the gate G1 and G2 of each transistor T1 and T2.
- a controlled voltage source or driver D1 and D2 hereinafter, voltage source
- Rg1 and Rg2 connected between each voltage source D1 and D2 and the gate G1 and G2 of each transistor T1 and T2.
- the transmitter E1 and E2 is shown, as well as the collector CL1 and CL2 of transistors T1 and T2.
- the voltage source is capable of imposing different voltage levels on its output depending on a control signal sent from, for example, the converter control unit.
- An example of the state of the art of voltage sources can be the hcpl-316j or hcpl-3120 of AVAGO, among others.
- the dynamics of the door-emitter voltage set the rate of variation of current by the transistor (current derivative) during its on and off and, therefore, the surges that appear in the parasitic inductances.
- the lower the ohmic value of the gate resistance the greater the current derivative.
- the overvoltages produced by the current variations in the parasitic inductances during the switching on and off of the transistors are more critical during switching off, where current derivatives greater than those of the ignition are reached.
- FIG. 4a Another alternative used to not work with voltages close to the limit voltages of the converter components can be seen schematically in Figure 4a. It consists of adding elements outside the converter that reduce the DC voltage of the photovoltaic generator from its open circuit voltage Voc to a safe value, from which the switching devices of the converter start to operate. Thus, for example, part of the energy of the photovoltaic panels can be consumed in controlled resistors (also known as chopper).
- controlled resistors also known as chopper
- Figure 4b Another method used in the prior art for not working with voltages close to the limit voltages of the converter components is that shown in Figure 4b, which consists of integrating an auxiliary switching element between the photovoltaic generator and the converter. or a linear power supply that reduces the voltage of the photovoltaic generator.
- FIG. 5.1a shows a wind topology formed by a wind generator of the type called "back-to-back" formed by two converters, a first AC / DC machine side converter and a second DC / AC network side converter.
- FIG. 5.2a shows a storage system formed by a set of electrochemical cells that form the battery (BAT) and a converter that can be DC / AC or DC / DC for connection to single-phase alternating voltage of the prior art.
- fig. 5.2b shows a storage system consisting of a set of electrochemical cells that form the battery (BAT) and a converter that can be DC / AC or DC / DC for connection to three-phase alternating voltage of the prior art.
- FIG. 5.2c shows a diagram showing the evolution of the current (I) and the voltage (V) in different battery operating states (discharge, constant current charge, constant voltage charge, float, equalization).
- I current
- V voltage
- BAT discharge, constant current load, constant voltage load, float
- the system and method proposed in the present invention solve the drawbacks of the state of the art indicated above because it allows modifying the switching on and off conditions of a switching device of an electronic converter, hereinafter converter, for example, DC / AC or DC / DC or AC / DC, allowing the switching device to work with voltages closer to its breaking voltage and extending the maximum continuous voltage.
- This modification can be performed dynamically, that is, the system can be activated or deactivated depending on the value of the DC voltage.
- the invention consists of a system and a method for controlling the current derivative by a switching device by means of the gate voltage thereof, especially during shutdown and thus controlling the surges that appear in the parasitic inductances.
- the elements of a switching device, three-terminal transistor type are the following: in the case of a collector IGBT (C), gate (G), emitter (E) and in the case of a drain MOSFET (D), gate (G), supplier (S).

- the common point has the negative connection of the voltage source and the transmitter of the switching device.
- the voltage source applies a positive voltage to the door of the switching device.
- the voltage is applied through the door resistors (first door resistance and second door resistance), in addition, the capacity is charged through the first circuit (formed by the first diode and the resistance).
- the order of magnitude of the resistance of the first circuit must be greater than the second door resistance so that the system of the invention does not affect the switching dynamics of the switching device, that is, so that the current flows to the door of the switching device.
- the voltages at the door of the switching device and in the capacity will be equal to those of the voltage source.
- the resistance of the first circuit will have a value that allows to load the capacity for the smallest ignition time that can be achieved in a switching device.

In this way, it is possible to control its dynamics by means of the first door resistance and the capacity value, causing the shutdown time to increase with respect to the existing solutions in the state of the art.
- connection element When the connection element is open, switching on and off is done through the first and second door resistors. Therefore, it is said resistors that set the switching on and off times of the switching device.
- the switching on and off orders of the switching device are consigned from a control unit of the converter to the voltage source or driver.
- the control unit of the connection device may be dependent or independent of the control unit of the converter, or be part of it.
- control system described above is integrated in the elementary switching cell formed by two switching devices so that one of said systems is added for each of the switching devices that said cell has.
- the switching devices have a delay between the on and off order that is applied to their door and their actual state (on - off).
- the other device In the elementary switching cell, to turn on one device, the other device must be turned off, otherwise it will cause a short circuit. Therefore, an order to switch on a device must be given a time later than the delay to turn off the other device. This time between the order to turn off a device and the order to turn on another device is called dead time.
- the downtime When the system of the invention is active, the downtime must be increased to prevent the two switching devices from being turned on at the same time, as the dynamics of the shutdown are slower.
- the proposed invention allows modifying the switching on and off conditions of the switching devices, through the switching on and off of the connecting device by means of the control unit, avoiding unnecessary losses in the switching devices when, for example, working at continuous voltages away from breaking tensions.
