PV inverter presentation

PV inverter can be divided according to the macro: 1. Ordinary inverter 2. Inverter / control one machine 3. Posts and Telecom Inverter 4. aerospace, military inverter used in various ways according to the inverter divided into: 1. Press the inverter output AC power of frequency: (1) frequency inverter frequency inverter frequency is 50 ~ 60Hz inverter (2) IF counter IF inverter frequency is generally 400Hz to tens kHz (3) high-frequency inverter high-frequency inverter frequency is generally more than a dozen KHz to MHz. 2. Press the number of the inverter output can be divided into: (1) single-phase inverter (2) three-phase inverter (3) multi-phase inverter 3. The inverter output power of the whereabouts of points can be divided into: (1) active 5000w inverter charger (2) in the form of passive inverter 4. The inverter main circuit can be divided into: (1) single-ended inverter (2) Push-Pull Inverter (3) half-bridge inverter (4) full-bridge inverter 5. Press the inverter main switch device types can be divided into: (1) thyristor inverter (2) transistor inverter (3) field effect inverter (4) insulated gate bipolar transistor (IGBT) inverter 6. Press the DC power supply can be divided into: (1) The voltage source inverter (VSI) (2) current source inverter (CSI) 7. Press the inverter control mode can be divided into: (1) Frequency Modulation (PFM) inverter (2) pulse width modulation type (PWM) inverter 8. The inverter switch circuit work can be divided into: (1) resonant inverter (2) fixed-frequency hard switching inverter (3) fixed-frequency soft switching inverter
