MOTOR C7 C6 AC LINE + Component Selection: Dsgn. Typ. Value Description D1 1A, 600V Boot strap supply diode – Ultra fast recovery C1 10-100uF, 50V Boot strap supply reservoir – Electrolytic, long life, low Impedance, 105°C (Note 5) C2 0.22-2.0uF, 50V Local decoupling/High frequency noise filters – Multilayer ceramic (Note 8) C3 10-100uF, 50V Control power supply filter – Electrolytic, long life, low Impedance, 105°C C4 22nF, 50V Fault lock-out timing capacitor – Multilayer ceramic (Note 4) C5 100pF, 50V Optional input signal noise filter – Multilayer ceramic (Note 1) C6 200-2000uF, 450V Main DC bus filter capacitor – Electrolytic, long life, high ripple current, 105°C C7 0.1-0.22uF, 450V Surge voltage suppression capacitor – Polyester/Polypropylene film (Note 9) CSF 1000pF, 50V Short circuit detection filter capacitor – Multilayer Ceramic (Note 6, Note 7) RSF 1.8k ohm Short circuit detection filter resistor (Note 6, Note 7) RSHUNT 5-100 mohm Current sensing resistor - Non-inductive, temperature stable, tight tolerance (Note 10) R1 10 ohm Boot strap supply inrush limiting resistor (Note 5) R2 330 ohm Optional control input noise filter (Note 1, Note 2) R3 10k ohm Fault output signal pull-up resistor (Note 3) Notes: 1) To prevent input signal oscillations minimize wiring length to controller (~2cm). Additional RC filtering (C5 etc.) may be required. If filtering is added be careful to maintain proper dead time. See application notes for details. 2) Internal HVIC provides high voltage level shifting allowing direct connection of all six driving signals to the controller. 3) FO output is an open collector type. Pull up resistor (R3) should be adjusted to current sink capability of the module. 4) C4 sets the fault output duration and lock-out time. C4 12.2E-6 x tFO, 22nF gives ~1.8ms 5) Boot strap supply component values must be adjusted depending on the PWM frequency and technique. 6) Wiring length associated with RSHUNT, RSF, CSF must be minimized to avoid improper operation of the SC function. 7) RSF, CSF set short-circuit protection trip time. Recommend time constant is 1.5us-2.0us. See application notes. 8) Local decoupling/high frequency filter capacitors must be connected as close as possible to the modules pins. 9) The length of the DC link wiring between C6, C7, the DIP’s P terminal and the shunt must be minimized to prevent excessive transient voltages. In particular C7 should be mounted as close to the DIP as possible. 10) Use high quality, tight tolorance current sensing resistor. Connect resistor as close as possible to the DIP’s N terminal. Be careful to check for proper power rating. See application notes for calculation of resistance value. |
