Class D Amplifier Schematic 1000w Pdf. This paper presents a new class d power amplifier suitable for sub woofer and woofer. 1000w output power in class d audio amplifier applications simplifies design due to integrated dead time generation and bi directional over current sensing optimized and compensated preset dead time selections for improved thd performances over temperature and noise shutdown function to protect devices from overloaded conditions.

Power amplifier apex ba1200 pcb layout pdf electronic circuit. The protection circuit stays in shutdown until the fault is re. This high power amplifier circuit is a class d power amplifier which has a high enough power to generate 1000w of power at 8 ohm impedance and also more power up to 2000w at 4 ohm impedance.
The proposed topology has high efficiency more than 90 when operating at nominal power.
This amplifier module must only be used and operated by a compe. Because of this the amplifier does not generate a lot of heat and does not require a big heat sink like linear class ab amplifiers do. The proposed topology has high efficiency more than 90 when operating at nominal power. For comparison the class b amplifier can only achieve a maximum efficiency of 78 5 in theory.
