L'étude et la réalisation d'un convertisseur 12V vers 220V de 1000W est un projet d'électronique de puissance ambitieux qui nécessite une compréhension rigoureuse de la gestion thermique et de la commutation des composants. Pour atteindre une telle puissance, le montage repose généralement sur une architecture à découpage utilisant des MOSFET de puissance (comme les IRFP3205 ou IRFZ44N) montés sur des dissipateurs thermiques conséquents pour évacuer la chaleur générée par le courant élevé au primaire du transformateur. Éléments clés du schéma technique
Un convertisseur de 1000W s'articule autour de trois sections principales :
L'oscillateur (Cœur de commande) : On utilise souvent des circuits intégrés comme le SG3525 ou le TL494 pour générer un signal PWM (Modulation de Largeur d'Impulsion). Ces puces permettent de réguler la fréquence (généralement 50 Hz ou 60 Hz) et d'assurer une stabilité que des oscillateurs simples à base de CD4047 ou NE555 ne peuvent garantir à forte charge.
L'étage de puissance : Pour 1000W, le courant d'entrée en 12V dépasse les 80-90 Ampères. Il est donc indispensable de paralléliser plusieurs MOSFET (par exemple 4 à 6 par canal) pour répartir la charge et réduire la résistance interne (

DC-DC Boost Stage: Elevates 12V DC to approximately 310V-340V DC using a high-frequency transformer and a PWM controller (like the SG3525 or TL494).
DC-AC Inverter Stage: Converts the high-voltage DC into 220V AC at 50Hz. For a "Pure Sine Wave" output, an SPWM driver module like the EGS002 is often used to control the H-bridge MOSFETs. 2. Required Components (1000W Specification)
To achieve a reliable 1000W output, components must be oversized to handle high current (up to 90A+ from the battery).
MOSFETs: 16x IRF3205 or IRLB4132 MOSFETs are recommended for a robust H-bridge.
Transformer: A 1000W rated transformer (either high-frequency ferrite for SMPS or large iron-core for low-frequency designs).
Control Module: EGS002 SPWM Driver for pure sine wave generation.
Cooling: Large aluminum heatsinks and a cooling fan are mandatory due to heat dissipation at 900W+ loads. 3. Basic Wiring Schematic Concept The primary circuit consists of the following flow: 1000W 12V DC Inverter Circuit Design | PDF - Scribd
