En la Fig. 1 se muestra un ejemplo de realización del sistema de caldeo activo de la presente invención para un convertidor de potencia 1 con un único módulo convertidor de potencia 2. El sistema de caldeo activo está comprendido por el convertidor de potencia 1, el termo-higrómetro 11 y el microprocesador 12. El convertidor de potencia está conectado a una fuente DC 3 mediante la unidad de desconexión 13 y por otro lado a la red AC 4. Así, cuando el convertidor de potencia está en modo producción, toma energía de la fuente DC 3 y la vierte a la red AC 4. En cambio, cuando el sistema se encuentra en modo noproducción, el sistema de caldeo activo es alimentado por la red AC con potencia eléctrica (activa y/o reactiva). An exemplary embodiment of the active heating system of the present invention for a power converter 1 with a single power converter module 2 is shown in Fig. 1. The active heating system is comprised of the power converter 1, the thermo-hygrometer 11 and microprocessor 12. The power converter is connected to a DC source 3 via the disconnection unit 13 and on the other hand to the AC 4 network. Thus, when the power converter is in production mode, it takes power from the DC 3 source and pour it into the AC 4 network. On the other hand, when the system is in nonproduction mode, the active heating system is powered by the AC network with electrical power (active and / or reactive).
En la Fig. 2 se muestra un ejemplo de realización del sistema de caldeo activo de la presente invención para un convertidor de potencia. El sistema de caldeo activo está comprendido por el convertidor de potencia 1 teniendo varios módulos convertidores de potenica 2a-2n, el termo-higrómetro 11 y el microprocesador 12. An exemplary embodiment of the active heating system of the present invention for a power converter is shown in Fig. 2. The active heating system is comprised of the power converter 1 having several power converter modules 2a-2n, the thermo-hygrometer 11 and the microprocessor 12.
En el ejemplo de realización mostrado en la figura 2, el convertidor de potencia 1 está formado por “n” módulos convertidores de potencia 2a-2n de los cuales se detallan dos de ellos 2a y 2n. Los módulos convertidores de potencia 2a-2n están conectados eléctricamente entre sí por medio de los embarrados DC 14 y los embarrados AC 15 que también conectan con la fuente DC 3 (fuente de corriente continua) y con la red AC (red de corriente alterna), respectivamente. Los embarrados en un convertidor de potencia son la pletinería de entrada a los módulos convertidores de potencia. Básicamente la pletinería son In the exemplary embodiment shown in Figure 2, the power converter 1 is formed by "n" power converter modules 2a-2n of which two of them 2a and 2n are detailed. The power converter modules 2a-2n are electrically connected to each other by means of DC busbars 14 and AC busbars 15 that also connect to DC source 3 (direct current source) and to the AC network (alternating current network) respectively. Busbars in a power converter are the input pletinería to the power converter modules. Basically pletinería are

forma, dependiendo de la consigna que cada módulo convertidor de potencia 2a-2n recibe del microprocesador 12, el comportamiento de cada módulo convertidor de potencia puede ser de inductivo o capacitivo. Si el número de módulos convertidores de potencia es par, el microprocesador 12 enviará a la mitad de los módulos convertidores de potencia una consigna inductiva y a la otra mitad una consigna de capacitiva, donde todas las consignas tienen la misma magnitud para que la suma total sea cero. En caso de que el número de módulos convertidores de potencia sea impar, el microprocesador 12 enviara un tipo de consigna (inductiva o capacitiva) a la mitad del total del número de módulos convertidores de potencia menos uno y la consigna opuesta (capacitiva o inductiva, respectivamente) al resto de módulos convertidores de potencia ajustando la magnitud de la consigna opuesta para que la suma total sea cero. Mediante fórmulas matemáticas, si el convertidor de potencia tiene “n” módulos convertidores de potencia, donde “n” es un número impar, el microprocesador 12 envía una consigna (inductiva o capacitiva) a (n-1)/2 módulos convertidores de potencia con una magnitud de consigna |A| y al resto de módulos convertidores de potencia, es decir, ((n-1)/2)+1, la consigna opuesta (capacitiva o inductiva, respectivamente) con una magnitud ((n-1)/(n+1)) |A|. Estas consignas son las preferidas porque optimizan el funcionamiento del sistema de caldeo, es decir, son las que hacen que el sistema de caldeo proporcione mayor cantidad de potencia (energía) calorífica. Cualesquiera otras consignas serían válidas mientras se cumpla la condición de que la suma de las consignas inductivas mas las consignas capacitivas sean cero. Expresado en forma de fórmula matemática: nI+|I|=nC+|C|, donde nI+nC = n; siendo “n” el número total de módulos convertidores de potencia (par o impar), “nI “ es el número de convertidores de potencia en comportamiento inductivo; “nC “ es el número de convertidores de potencia en comportamiento capacitivo; |I| es la amplitud de la consigna inductiva e |C| es la magnitud de la consigna capacitiva. Thus, depending on the setpoint that each power converter module 2a-2n receives from the microprocessor 12, the behavior of each power converter module can be inductive or capacitive. If the number of power converter modules is even, microprocessor 12 will send an inductive setpoint to half of the power converter modules and a capacitive setpoint to the other half, where all setpoints have the same magnitude so that the total sum is zero. If the number of power converter modules is odd, the microprocessor 12 will send a setpoint type (inductive or capacitive) to half of the total number of power converter modules minus one and the opposite setpoint (capacitive or inductive, respectively) to the rest of the power converter modules by adjusting the magnitude of the opposite setpoint so that the total sum is zero. By mathematical formulas, if the power converter has "n" power converter modules, where "n" is an odd number, microprocessor 12 sends a setpoint (inductive or capacitive) to (n-1) / 2 power converter modules with a setpoint magnitude | A | and the other power converter modules, that is, ((n-1) / 2) +1, the opposite setpoint (capacitive or inductive, respectively) with a magnitude ((n-1) / (n + 1)) | A |. These setpoints are preferred because they optimize the operation of the heating system, that is, they are what make the heating system provide the greatest amount of heat power (energy). Any other setpoints would be valid as long as the condition that the sum of the inductive setpoints plus the capacitive setpoints is zero is fulfilled. Expressed in the form of a mathematical formula: nI + | I | = nC + | C |, where nI + nC = n; where "n" is the total number of power converter modules (odd or even), "nI" is the number of power converters in inductive behavior; "NC" is the number of power converters in capacitive behavior; | I | is the amplitude of the inductive setpoint e | C | It is the magnitude of the capacitive setpoint.
Opcionalmente el sistema de caldeo activo puede incrementar adicionalmente la temperatura interior del convertidor de potencia 1 mediante la energización (paso de corriente) de los embarrados DC 14. El caldeo de los embarrados es ventajoso cuando el convertidor de potencia se sitúa en climas muy fríos o muy húmedos. Optionally, the active heating system can additionally increase the internal temperature of the power converter 1 by energizing (current flow) of the DC busbars 14. The heating of the busbars is advantageous when the power converter is in very cold climates or very wet
La alimentación del sistema de caldeo del ejemplo de realización mostrado en la figura 2 se realiza mediante la Red AC 4. Esta forma de alimentación y por tanto, de energización de los módulos convertidores de potencia implica el proceso de carga suave anteriormente descrito para el circuito de carga suave 9. Esta forma de alimentación es ventajosa porque no necesita de fuentes de alimentación adicionales. Cuando se utiliza la The heating system is fed into the example of embodiment shown in Figure 2 by means of the AC 4 network. This form of power supply and, therefore, of energizing the power converter modules implies the smooth charging process described above for the circuit Soft charging 9. This form of feeding is advantageous because it does not need additional power supplies. When you use the
