PV inverter protection and recovery test

The three-level neutral point clamped (NPC) topology is gaining significant popularity in high-power converters, whether it's for DC-DC isolated converters in high-power chargers or high-power grid-tied solar inverters. One challenge associated with these converters is the uneven distribution of losses, which limits the ability of power electronics designers to size them optimally for maximum power efficiency. The active neutral point clamped (ANPC) topology offers an inherent advantage by introducing redundant switching states through the replacement of diodes with active switches. These redundant switching states help address the uneven loss distribution, thereby improving throughput and reducing the commutation loop length to minimize loop inductance. The following presentation from Infineon Technologies provides a concise overview of the ANPC topology with optimized PWM Strategy.

What is the difference between Schottky diodes and ordinary diodes? The main differences between Schottky diodes and ordinary diodes are as follows: 1. The working principle is different. Based on the unidirectional conductivity of the PN junction, the current can flow through the PN junction at the forward voltage, and the PN junction blocks the current flow under the reverse voltage. Schottky diodes are based on the principle of a metal-semiconductor junction, where electrons flow from the metal to the semiconductor to form a current in the forward direction and almost no current in the reverse direction. 2. The forward pressure drop is different. Conventional diodes have a high forward voltage drop, typically between 0.6V and 1.0V, while Schottky diodes have a low forward voltage drop, typically between 0.2V and 0.7V, which gives Schottky diodes an advantage in low-voltage applications. 3. The reverse leakage current is different. Schottky diodes have a large reverse leakage current and are not suitable for use as reverse blocking components; Ordinary diodes have a small reverse leakage current and are typically used for reverse blocking tasks. 4. The reverse withstand voltage is different. The reverse withstand voltage of Schottky diodes is lower than that of ordinary diodes, generally less than 200V; Conventional diodes have a high reverse withstand voltage. 5. The recovery time is different. Schottky diodes have a shorter reverse recovery time than ordinary diodes, making Schottky diodes operate more frequently; Ordinary diodes have a longer reverse recovery time. 6. The junction capacitance is different. Schottky diodes have a smaller junction capacitance than ordinary diodes, which makes Schottky diodes more suitable for high-frequency applications. 7. Different application scenarios. Schottky diodes are suitable for low-voltage, high-current application scenarios, such as switching power supplies, solar inverters, high-frequency signal processing, etc.; Ordinary diodes are suitable for high-voltage, low-current application scenarios, such as rectifiers, voltage regulators, signal amplifiers, etc. Phone/Whatsapp/WeChat:+8613632797880 Email：quendy@omida.net #IC #capacitors #transistors #diodes #IGBT #semiconductors #electroniccomponents #PCBA #integratedcircuit
